FM 90-5
Jungle Operations
About this edition
The jungle doesn't care about your training schedule. It rots your gear, hides the enemy ten meters away, and turns a routine patrol into a survival exercise. This manual teaches you to fight in it anyway.
FM 90-5 is the U.S. Army's manual on military operations in jungle environments — covering movement, patrolling, offensive and defensive operations, and survival in tropical terrain. Published in 1982, it codifies lessons from Vietnam and decades of jungle warfare experience.
Topics include:
- The jungle environment — types, terrain, weather, and wildlife hazards
- Movement and navigation under triple-canopy
- Offensive operations — ambush, raid, and attack in jungle terrain
- Defensive operations and base camp security
- Patrolling techniques specific to dense vegetation
- Water procurement, disease prevention, and jungle survival
- Helicopter operations in restricted landing zones
