“In the jungle, the side that sees first decides first, acts first and survives.”

Introduction

Small-uncrewed aerial systems (s‑UAS) have proliferated rapidly across contemporary conflicts due to their low cost, commercial availability, and ease of adaptation for military use. Once limited to technologically advanced states, s‑UAS are now employed by both state and non‑state actors to conduct intelligence, surveillance and reconnaissance, targeting, and precision strike at the tactical level. Recent conflicts, including the war in Ukraine, have demonstrated that s‑UAS are integral to close combat operations, enabling persistent battlefield observation and significantly reducing tactical freedom of manoeuvre.

The employment of s‑UAS within the Australian Defence Force’s Primary Operating Environment (POE) will become a decisive factor in contemporary operations. Operating across vast distances and close complex terrain, the ADF faces adversaries who increasingly assume persistent aerial observation and rapid tactical adaptation. In this context, s‑UAS offer enhanced situational awareness, improved force protection, and greater decentralisation of combat power, while simultaneously reshaping tactics and survivability in close country operations. Understanding the outcomes of s‑UAS integration is therefore essential to maintaining tactical overmatch and operational relevance within the Indo‑Pacific operating environment.

The ADF’s POE encompasses the geographic and strategic space in which Australia is most likely to employ military power to protect its national interests. Centred on Australia and extending through its immediate neighbourhood into the broader Indo‑Pacific region spanning maritime, littoral, archipelagic, air, and land domains as well as the increasingly contested space, cyber, and information environments. The POE is characterised by vast distances, complex and restrictive terrain, dense urban and coastal populations, and significant climatic and environmental challenges. Operations are likely to occur in close and complex country; jungles, islands, urban areas, and littoral zones; where mobility is constrained, sustainment is difficult, and forces are likely to be persistently observed and contested.

This essay aims to examine the role and impact of s‑UAS within the Australian Defence Force’s POE. It seeks to analyse the employment of s‑UAS influencing close country operations, particularly in the complex terrain characteristics of the Indo‑Pacific. The essay further aims to assess the operational advantages and challenges associated with s‑UAS integration including effects on situational awareness, manoeuvre, survivability, and mission command. Finally, it aims to identify key implications for ADF force design, tactics, and training necessary to retain tactical overmatch against state and non‑state adversaries operating in contested, multi‑domain environments.

Role and impact within the POE

The ADF POE is characterised by joint, integrated, and contested operations conducted across complex littoral, archipelagic, urban, and jungle terrain. Within this environment, s‑UAS have become a critical capability, delivering disproportionate tactical impact relative to their size and cost. Their role extends beyond traditional intelligence, surveillance and reconnaissance (ISR), shaping decision‑making, lethality, survivability, and the conduct of distributed operations.

The primary role of s‑UAS within the POE is to provide organic, responsive ISR at the lowest levels of command. S-UAS enable section, platoon, and combat team commanders to observe beyond line of sight, detect enemy activity, and better understand terrain, obstacles, and avenues of approach in near real time. In a transparent and information‑dense battlespace, where adversaries actively seek to deny situational awareness through dispersion and concealment, s‑UAS reduce uncertainty and compress decision cycles. This directly supports tempo and initiative, reinforcing the ADF’s emphasis on mission command and decentralised execution.

S‑UAS also have a significant impact on the application of force. By enabling rapid target acquisition, confirmation, and battle damage assessment, s‑UAS enhance the precision and effectiveness of both organic and joint fires. This precision is particularly important in the POE, where operations conducted are often in close proximity to civilian populations and critical infrastructure. Improved target discrimination supports proportionality, minimises collateral damage, and preserves legitimacy that is central to sustaining freedom of action.

Force protection is another key contribution of s‑UAS. Their employment during movement, halts, and defensive activities provides early warning of ambushes and enemy reconnaissance. In an environment defined by persistent surveillance and rapid targeting, the side that detects first frequently gains a decisive advantage. S‑UAS help mitigate this risk by restoring situational awareness at the tactical edge, improving survivability against both state and non‑state threats.

The POE places particular emphasis on distributed and littoral operations, where small, semi‑autonomous elements operate across wide areas with limited access to higher‑end ISR and fires. S‑UAS are well suited to this construct, bridging ISR gaps between dispersed elements and reducing reliance on scarce theatre‑level assets. Their portability, low logistic burden, and relative affordability enable mass and redundancy, allowing losses through enemy action or electronic warfare as acceptable as a tactical cost rather than a mission‑limiting risk.

Notwithstanding their impact, s‑UAS are vulnerable to electronic attack, cyber exploitation, and kinetic counter‑UAS systems. Their effectiveness therefore depends on integration within a combined‑arms and multi‑domain approach, supported by appropriate training, SOPs, and command and control arrangements.

In summary, s‑UAS are no longer optional enablers within the ADF POE. They are a foundational capability that enhances decision advantage, lethality, and protection while enabling distributed operations. Their greatest impact lies in empowering junior leaders and embedding information superiority at the tactical level, fundamentally shaping how the ADF operates in its primary operating environment.

Close country operations are characterised by restricted observation, compressed engagement ranges, degraded communications, and limited manoeuvre space. They occur in terrain such as jungle, dense vegetation, urban areas, mountainous regions, plantations, and complex littoral environments. These conditions traditionally favour the defender or ambusher who can exploit concealment, covered movement, obstacles, and local knowledge. The employment of s‑UAS has significantly influenced close country operations by improving tactical observation, accelerating decision-making, enhancing force protection, and increasing the precision of fires and manoeuvre.

The most significant contribution of s‑UAS within close country is the provision of organic intelligence, surveillance and reconnaissance at the lowest tactical level. In jungle or urban terrain, ground commanders are often unable to see beyond the next ridgeline, tree line, compound, street corner, or building. s‑UAS allow section, platoon, and combat team commanders to gain an aerial perspective without exposing scouts or reconnaissance patrols to unnecessary risk. This enables friendly forces to identify enemy positions, detect movement, locate obstacles, assess routes, and confirm terrain before committing troops. In effect, s‑UAS reduce the uncertainty that normally dominates close country operations.

This improved situational awareness directly affects manoeuvre. Close country frequently canalises forces along roads, tracks, creek lines, jungle trails, or urban corridors making them vulnerable to ambush and obstacles. s‑UAS provide route reconnaissance, flank observation, and overwatch allowing commanders to detect threats before friendly forces enter an engagement area. This does not remove risk, but allows risk to be identified earlier and managed more effectively. Commanders can adjust routes, change formations, delay movement, employ suppressive fires, or bypass enemy positions. As a result, s‑UAS help maintain tempo while improving security.

S‑UAS also influence the employment of fires in close country. In restricted terrain, targets are difficult to identify and may be located close to civilians, friendly forces, or protected infrastructure. S‑UAS assist with target confirmation, fire correction, and battle damage assessment. This improves the accuracy of direct and indirect fires and reduces reliance on speculative or area-based engagement. In urban operations, where the legal, moral, and strategic consequences of collateral damage are significant, s‑UAS support more discriminate use of force. They also enable faster sensor-to-shooter links where an observed target can be rapidly passed to mortars, artillery, direct fire weapons, or supporting aircraft.

Force protection is another major area of influence. Close country operations expose soldiers to sudden contact, ambush, snipers, improvised explosive devices, and infiltration. S‑UAS can provide early warning during halts, defensive tasks, clearance operations, and movement through danger areas. They can observe likely enemy approaches, monitor dead ground, and identify suspicious activity before it develops into contact. This shifts part of the burden of observation away from dismounted soldiers and allows commanders to preserve combat power.

However, s‑UAS are not a complete solution. Dense canopy, buildings, terrain masking, weather, battery endurance, and signal obstruction can limit their effectiveness in close country. They are also vulnerable to small arms fire, electronic warfare, jamming, and detection. Poorly disciplined employment may compromise friendly positions through visual or electronic signature. For this reason, s‑UAS must integrate with fieldcraft, camouflage, deception, dismounted reconnaissance, communications planning, and combined arms tactics. Units must train to continue operating when s‑UAS are lost, denied, or degraded.

Case Study: Thai-Cambodian Border

The Thai-Cambodian border, particularly around the Preah Vihear temple area, provides a useful close country case study. The border region includes jungle, steep terrain, restricted approaches, observation posts, and culturally sensitive infrastructure. During periods of tension and armed clashes, forces operated in terrain where visibility was limited, positions were difficult to confirm, and indirect fire carried significant tactical and political risk. In such an environment, s‑UAS would strongly influence operations by improving observation of ridgelines, tracks, suspected firing points, and troop movement without requiring soldiers to expose themselves during reconnaissance.⁴

In this case, s‑UAS employment would support three key tasks. First, they would assist commanders in confirming the location and activity of opposing forces in terrain where ground observation is restricted. Second, they would improve force protection by monitoring likely infiltration routes, patrol approaches, and dead ground near forward positions. Third, they would support more controlled escalation by providing visual confirmation before fires or manoeuvre are authorised. This is particularly important in a politically sensitive border dispute where misidentification or disproportionate response could produce strategic consequences.

The case also highlights limitations. Dense vegetation and rugged ground could reduce the effectiveness of small drone sensors. Electronic emissions might expose friendly activity. The proximity of opposing forces could make s‑UAS vulnerable to small arms fire or capture. Nevertheless, the Thai-Cambodian border demonstrates how s‑UAS can provide tactical advantage in close country by improving situational awareness, supporting restraint, and reducing the risk of surprise.

In conclusion, s‑UAS significantly influence close country operations by improving observation, enabling safer manoeuvre, enhancing precision, and strengthening force protection. Their greatest value is providing junior commanders with timely information in terrain that normally conceals the enemy. They do not replace fieldcraft or reconnaissance, but they amplify both when integrated into disciplined combined arms procedures.

Operational advantages and challenges

S‑UAS have transformed the tactical battlefield, particularly in close country environments characterised by dense vegetation, urban clutter, restricted visibility, and constrained manoeuvre. These systems provide enhanced situational awareness, greater lethality, and extended operational reach, but they also introduce vulnerabilities, command challenges, and logistical burdens. Their impact is most evident in the areas of situational awareness, manoeuvre, survivability, and mission command.

The greatest advantage of s‑UAS is improved situational awareness. In terrain where vegetation, terrain folds, and urban obstacles limit observation, drones provide commanders with an aerial perspective that reveals enemy positions, movement patterns, and terrain obstacles. Real-time video feeds reduce uncertainty, support route planning, and enable faster decision-making. Their ability to conduct persistent surveillance also improves intelligence preparation of the battlespace and pattern-of-life analysis.

However, the large volume of information generated by s‑UAS can create cognitive overload and strain command networks. Environmental factors such as dense canopy, GPS limitations, and electromagnetic interference may also degrade performance. Furthermore, reliance on drone-derived intelligence creates vulnerabilities if systems are jammed, spoofed, or otherwise compromised.

S‑UAS enhance manoeuvre by enabling informed movement and route selection. Reconnaissance ahead of advancing forces allows units to identify threats, avoid obstacles, and maintain tempo. They also improve combat effectiveness by supporting precision targeting, artillery adjustment, and coordination between manoeuvre and fires, enabling smaller units to generate greater combat effects.

Challenges arise when forces become overly reliant on drone confirmation before acting, potentially slowing decision-making and reducing initiative. The requirement to carry batteries, spare parts, and control equipment also increases soldier loads and can reduce mobility during dismounted operations. Additionally, drone launches may generate detectable electromagnetic signatures that reveal friendly intent and compromise surprise.

S‑UAS improve survivability by reducing the need for personnel to conduct hazardous reconnaissance and by providing early warning of threats. Enhanced detection of ambushes, enemy concentrations, and obstacles improves force protection. Drones can also support deception by misleading adversaries about friendly locations and intentions.

Conversely, s‑UAS introduce new vulnerabilities. Their acoustic and electronic signatures can reveal friendly activity, while adversaries may employ jamming, cyber interference, and kinetic counter‑UAS systems. The Myanmar conflict highlights these risks, with both military and resistance forces using drones extensively for surveillance and strike missions. As drone proliferation increases, traditional concealment becomes less effective and all forces are exposed to persistent aerial observation.

S‑UAS can support mission command by providing a shared understanding of the battlespace. Real-time feeds enable dispersed units to make informed decisions consistent with commander’s intent, particularly when communication with higher headquarters is degraded. Improved coordination and visual confirmation of battlefield conditions can enhance decentralised execution.

However, access to live drone feeds may encourage micromanagement from higher headquarters, reducing subordinate autonomy. Dependence on digital networks also creates vulnerabilities to communication disruption, while training requirements and interoperability challenges can complicate effective integration across larger or coalition forces.

The integration of s‑UAS offers significant advantages in situational awareness, manoeuvre, survivability, and mission command – helping overcome the challenges of close country operations. Yet these benefits come with environmental, electronic, logistical, and command-related risks. Their effectiveness ultimately depends on balanced employment; resilient systems; and appropriate doctrine, training, and sustainment. In close country, s‑UAS are both a force multiplier and a potential vulnerability, requiring thoughtful integration into tactical operations.

Case Study: Myanmar Civil War

The Myanmar Civil War demonstrates the growing importance of s-UAS in close country environments dominated by dense jungle, mountainous terrain, and dispersed rural settlements. These conditions restrict visibility, complicate manoeuvre, and degrade communications making even basic reconnaissance difficult. Within this context, both resistance groups (PDFs and EAOs) and the Tatmadaw have integrated s‑UAS to enhance battlefield effectiveness.

The primary operational advantage of s‑UAS in Myanmar is improved situational awareness. Resistance forces, often lacking formal reconnaissance assets, have leveraged commercial drones to observe troop movements, identify bases, and monitor supply routes. This aerial perspective is particularly valuable in jungle environments where ground observation is limited by vegetation and terrain. Even short-duration drone flights allow units to reduce uncertainty, plan ambushes, and avoid superior forces.

S‑UAS also support manoeuvre by enabling more informed movement. Resistance units use drones to scout routes and identify checkpoints, allowing them to exploit gaps and maintain mobility. Additionally, improvised munitions dropped from drones provide a limited precision strike capability, allowing attacks on fixed positions without direct contact.

However, these benefits are constrained by significant challenges. Dense canopy often limits visibility from above, forcing drones to fly low where they are vulnerable to small-arms fire and detection. Technical limitations, including poor signal range and unreliable equipment, further reduce effectiveness. Logistically sustaining drone operations in austere environments, especially batteries and spare parts, is difficult.

From a survivability perspective, s‑UAS reduce the need for risky reconnaissance but introduce new vulnerabilities. Their acoustic and electronic signatures can reveal friendly activity while widespread use means both sides are exposed to aerial observation. Overall, the Myanmar conflict highlights s‑UAS as a force multiplier in close country, but one whose effectiveness depends heavily on environmental conditions, sustainment, and tactical adaptation.

Force Design, Tactical and Training Implications

Maintaining tactical overmatch against state and non-state adversaries employing s-UAS requires the ADF to adapt its force design, tactics, and training to account for a battlespace characterised by persistent surveillance, contested electromagnetic spectrum, and rapid technology proliferation. The widespread use of low-cost, commercially derived drones – demonstrated in recent conflicts – has compressed the sensor-to-shooter cycle and eroded traditional force protection assumptions.

ADF force design must emphasise a layered, scalable c-UAS architecture integrated from section to joint-task force level. High-end air defence systems alone are insufficient against small, low-signature drones; instead, a mix of kinetic (small-calibre weapons, intercept drones) and non-kinetic effects (EW, cyber and directed energy) is required.10 These capabilities must be organic to manoeuvre elements in order to reduce reliance on scarce specialist assets.

A key implication is the normalisation of organic s-UAS across all combat elements. Platoon-level units require persistent ISR drones and loitering munitions to compete in reconnaissance and precision strike. These systems must be interoperable with joint networks, enabling rapid integration into fires and intelligence systems thereby accelerating the kill chain. System design needs to consider operations in degraded, denied, or disrupted environments, incorporating anti-jam communications, spectrum agility, and autonomy. Navigation redundancy (e.g. inertial and visual navigation) reduces reliance on GPS, while distributed architectures mitigate single points of failure. Force design should also prioritise attritability, accepting loss of low-cost systems while preserving combat effectiveness.

Tactically, the ADF must assume ubiquitous adversary ISR provided by s-UAS. This fundamentally alters survivability. Camouflage, concealment, dispersion, and deception must be systematically applied across all operations, incorporating multispectral signature management to counter visual, thermal, and electronic detection. Manoeuvre must become more fluid and less predictable. Units should emphasise rapid displacement, small-unit dispersion, and terrain masking to mitigate drone-enabled targeting. Static positions require overhead protection or deception measures (decoys, false emissions). Emissions discipline becomes essential as RF signatures can cue drone reconnaissance and strike.

The ADF must also adopt offensive s-UAS employment as a core tactical function. Swarming, coordinated ISR-strike packages, and loitering munitions enable low-cost precision effects. Integration with EW allows disruption or hijacking of adversary drones, transforming the electromagnetic spectrum into a manoeuvre space. Counter-reconnaissance is equally important. Identifying and targeting enemy drone operators, ground control stations, and logistics nodes can degrade adversary s-UAS effectiveness. In littoral environments, likely for ADF operations, tactics must account for cluttered terrain and dense electromagnetic activity, leveraging cover while mitigating reduced detection ranges.

Training must reflect the reality of continuous drone presence and electromagnetic contestation. Collective training should routinely incorporate both friendly and adversary s-UAS, conditioning forces to operate under persistent observation and intermittent attack. This includes exposure to realistic EW effects such as GPS denial, data-link disruption, and degraded communications. A broad baseline of drone literacy across the force is essential. All personnel should understand basic s-UAS capabilities, vulnerabilities, and countermeasures – while specialists require advanced proficiency in EW, drone operations, and data exploitation. This supports distributed operations where small units act independently but remain networked.

Simulation and synthetic training environments are critical to replicating high-density complex drone threats that are impractical to generate in live training. Blended live-virtual constructive systems enable scalable and repeatable scenarios, improving decision-making under pressure. Leadership development must reinforce mission command with degraded environments. Junior leaders need the competence to act decisively when communications are disrupted and threats evolve rapidly. Training should emphasise adaptability, rapid judgement, and the integration of s-UAS into manoeuvre planning and execution.

Conclusion

The employment of s‑UAS is reshaping close-country operations across the Indo‑Pacific, where dense jungle, urban littorals, and archipelagic terrain constrain visibility, mobility, and communications. In such environments, s‑UAS provide a decisive situational awareness advantage; enabling persistent, low-cost ISR beyond visual line-of-sight limitations. Small units can rapidly identify threats, navigate complex terrain, and cue fires with greater precision, thereby compressing the sensor-to-shooter cycle.

However, this advantage is contested. Adversary s‑UAS create continuous surveillance, eroding concealment and increasing vulnerability to detection and precision strike. In close country, where terrain provides cover, overhead observation now exposes manoeuvre corridors, logistics nodes, and command elements. As a result, manoeuvre becomes more deliberate and dispersed relying on terrain masking, deception, and displacement to avoid targeting. S‑UAS also enhance survivability when used defensively but can equally degrade survivability if adversary capabilities are not countered.

The integration of s‑UAS supports mission command by improving shared understanding across dispersed forces, particularly in communications-degraded environments common in the Indo‑Pacific. However, reliance on digital networks introduces vulnerabilities to EW, jamming, and cyber disruption potentially fragmenting command and control.

Operationally, s‑UAS integration presents both advantages and challenges: enhanced ISR, targeting, and tempo versus increased electromagnetic signature, cognitive load, and exposure to counter‑s-UAS effects.

Key implications for the ADF include embedding organic s‑UAS and counter‑s-UAS capabilities at small-unit level; designing systems resilient to degraded, denied environments; and adopting tactics that prioritise signature management, dispersion, and deception. Training must normalise operating under persistent drone threat, develop force-wide drone literacy, and reinforce mission command under contested conditions. Collectively, these adaptations are essential for maintaining tactical overmatch in complex Indo‑Pacific environments.
