U.S. Army Air Assault Brigade Finds AI Tools Ill-Suited for Tactical Planning
After hands-on testing, a U.S. Army air assault brigade concluded that large language models (LLMs) are fundamentally limited for tactical planning. Colonel Ryan Bell stated that LLMs cannot effectively understand three-dimensional space, making them inadequate for developing courses of action in complex air assault operations.

Highlights
- Colonel Ryan Bell of a U.S. Army air assault brigade stated that LLMs do not truly understand three-dimensional space and are therefore inadequate for developing tactical courses of action.
- Air assault operations require complex 3D planning covering helicopter flight paths, terrain elevation, and aerial maneuver, exposing a fundamental mismatch with current text-based AI systems.
- The U.S. Army's evaluation found that directly applying LLMs to air assault operational planning risks producing unrealistic or operationally unsafe plans.
- AI tools have shown potential in intelligence analysis, logistics, and administrative tasks, but their use in spatial tactical planning requires careful, case-by-case assessment.
- The findings highlight that the gap between AI technical capabilities and actual combat operational requirements remains a critical barrier to broader military AI integration.
U.S. Army Air Assault Brigade Finds AI Tools Ill-Suited for Tactical Planning
A U.S. Army air assault brigade has concluded, following real-world testing of artificial intelligence tools, that current large language models (LLMs) have fundamental limitations when applied to tactical planning.
"Large language models don't truly understand three-dimensional space, so they aren't good at developing courses of action," said Colonel Ryan Bell of the air assault brigade.
The 3D Spatial Comprehension Bottleneck
The finding highlights a core challenge facing generative AI technology in military applications. Tactical planning relies heavily on precise understanding of terrain, elevation, flight paths, and situational awareness in three-dimensional space. Existing LLMs are, by nature, text-based systems with considerably limited capacity for 3D spatial perception and reasoning.
Air assault operations — encompassing helicopter air landings, aerial maneuver, and three-dimensional envelopment — place exceptionally high demands on spatial planning. Colonel Bell's assessment suggests that directly applying LLMs to this type of operational planning could produce unrealistic or operationally unsafe courses of action.
Military AI Integration Still Requires Careful Evaluation
The evaluation serves as a reminder that while AI has demonstrated meaningful potential in areas such as intelligence analysis, logistics management, and administrative tasks, its suitability for tactical-level applications requiring precise spatial judgment must be carefully assessed.
U.S. military units continue to explore appropriate use cases for AI tools, but this case illustrates that the gap between current technical capabilities and real-world operational requirements remains a critical issue that must be squarely addressed as the armed forces pursue broader AI integration.
