This field manual establishes doctrine (fundamental principles) for tactical counterinsurgency (COIN) operations at the company, battalion, and brigade level. It is based on lessons learned from historic counterinsurgencies and current operations. This manual continues the efforts of FM 3-24, Counterinsurgency, in combining the historic approaches to COIN with the realities of today’s operational environment (OE)—an environment modified by a population explosion, urbanization, globalization, technology, the spread of religious fundamentalism, resource demand, climate change and natural disasters, and proliferation of weapons of mass destruction..

The target audience is commanders, staff, and Soldiers of US Army units up to brigade level.

This manual applies to the Active Army, the Army National Guard (ARNG)/Army National Guard of the United States (ARNGUS), and the US Army Reserve (USAR) unless otherwise stated.
