This field manual provides a doctrinal framework for the Infantry weapons company assigned to Infantry battalions in an Infantry brigade combat team (IBCT). It is a companion to FM 3-21.10, The Infantry Rifle Company, much of which applies to the Infantry weapons company and as such will not be repeated herein. This manual will discuss on the unique characteristics of the Infantry weapons company, including principles, tactics, techniques, procedures, and terms and symbols. It will also cover what the Infantry weapons company brings to the Infantry battalion and the battlefield. Among topics covered in FM 3-21.10 but omitted here are the characteristics and fundamentals of urban operations, risk management and fratricide avoidance, heavy and Stryker unit employment, sniper employment, improvised explosive devices, operations in a chemical, biological, radiological, and nuclear (CBRN) environment, media considerations, pattern analysis, and situational understanding.
