Jungle warfare or woodland warfare is warfare in forests, jungles, or similar environments. The term encompasses military operations affected by the terrain, climate, vegetation, and wildlife of densely wooded areas, as well as the strategies and tactics used by military forces in these situations and environments.
The jungle has a variety of effects on military operations. Dense vegetation can limit lines of sight and arcs of fire, but can also provide ample opportunity for camouflage and plenty of material with which to build fortifications. Jungle terrain, often without good roads, can be inaccessible to vehicles and so makes logistical supply and transport difficult, which in turn places a premium on air mobility. The problems of transport make engineering resources important as they are needed to improve roads, build bridges and airfields, and improve water supplies. Jungle environments can also be inherently unhealthy, with various tropical diseases that have to be prevented or treated by medical services. The terrain can make it difficult to deploy armoured forces, or any other kind of forces, on a large scale. Successful jungle fighting emphasizes effective small unit tactics and leadership.
