U.S. Army Counterguerrilla Operations Handbook

The Army's official handbook on how to fight guerrilla insurgencies.

The U.S. Army has studied every condition under which it may be called into action, and the possibility of a guerrilla insurgency is no exception. As many have noted, the United States military will likely engage in more small- and medium- scale hostilities against guerrillas than in classic Cold War European Theater scenarios. Available here for the first time is the Army's official document on guerrilla insurgencies-such as the insurgency in Iraq-and how to deal with them.
The U.S. Army Counterguerrilla Operations Handbook identifies what constitutes an insurgency, the conditions that foster insurgencies, likely insurgents, and the overall goals of insurgent groups. It then goes on to describe in detail the specifics of how to overcome guerrilla operations in conventional and unconventional conflicts, including:

Vulnerable populations
Offensive and defensive operations
How to counter common guerrilla tactics
Reconnaissance, surveillance, and intelligence
Tunnel combat and hit-and-run ambushes
Smoke, flame, herbicides, and riot control agents
Civil disturbances and searches
Psychological operations

In addition, the handbook describes how strategic and political considerations can outweigh military considerations, and gives guidance on when the military's mission is accomplished.
