This publication, Marine Corps Reference Publication MCRP 3-10A.2 (Formerly MCRP 3-10A.1 and MCWP 3-11.1) Infantry Company Operations 22 February 2018, is a complete rewrite of MCWP 3-11.1, Marine Rifle Company/Platoon. This publication contains a new mission statement for the infantry company that better reflects current reality. It also covers the range of military operations that deployed infantry companies deal with today or may deal with tomorrow. Despite this extended coverage, MCWP 3-11.1 is not intended to be all encompassing. There are many aspects of infantry company operations that are not addressed herein because a specific publication already exists for that aspect. To cover it here would be redundant. This publication does serve, however, as the basic warfighting company publication and is to be used in conjunction with appropriate small unit, battalion, and other Marine Corps doctrinal and warfighting publications. This publication is intended for the infantry company commander and his staff. It is a foundational document that assists in the preparation and execution of company level operations in the current operational environment.
