More reach, more to carry, more to learn: How soldiers wrestled with drones in the Mojave Desert

DefenseScoop  |  Drew F. Lawrence

More than 8,500 U.S. Army soldiers from the 4th Infantry Division integrated First-Person View drones into scout operations during Project Convergence Capstone 6 at Fort Irwin, California. The ten-day exercise tested platforms like the Neros Archer, Anduril Bolt-M, and Teledyne FLIR Rogue 1 against simulated opposition forces to evaluate Next Generation Command and Control prototype capabilities.

Dismounted troops faced operational trade-offs as unmanned aerial systems expanded standoff reconnaissance and organic precision strike capabilities but added substantial battery and equipment weight to dismounted infantry loads. While Bradley Fighting Vehicle crews successfully employed loitering munitions to engage targets from heavy cover without exposing armored positions, extreme desert heat, radio signal masking, and airspace coordination constraints reduced operational drone endurance and range below vendor-advertised specifications. These tactical friction points reveal systemic challenges in translating static, entrenched small-UAS tactics from the Ukrainian conflict into highly mobile, expeditionary American mechanized doctrine.

Comment

The field trial of the Anduril Bolt-M and Teledyne FLIR Rogue 1 during Project Convergence Capstone 6 exposes a critical sustainment bottleneck in small unmanned systems for dismounted scouts. Transporting upwards of eleven specialized lithium batteries and heavy ground control stations alongside standard anti-tank munitions rapidly exhausts infantry payload capacity during long-duration desert reconnaissance. Without standardised, swappable power architectures across multi-vendor loitering platforms, forward units remain tied to vehicle resupply hubs or forced to discard critical sensor range. Thermal degradation of battery longevity under severe Mojave Desert conditions further reduces effective tactical flight times below published contractor specifications.

Strategic Question for Discussion

If thermal environmental limits and battery weight penalties demonstrated during Project Convergence Capstone 6 continue to constrain dismounted operations, which factor will ultimately determine the tactical employment of platforms like the Anduril Bolt-M and Teledyne FLIR Rogue 1 — reducing organic soldier payload or accepting lower operational standoff distances?
