The United States Marine Corps Reserve is a vital component of the Marine Corps, comprising talented and dedicated individuals who serve part-time while maintaining civilian careers. The Reserve plays a crucial role in supporting the Active Component, providing a scalable and responsive force that can be quickly mobilized to meet a wide range of operational requirements. With a rich history dating back to 1916, the Marine Corps Reserve has evolved to become an indispensable part of the Marine Corps' total force, with units spread across the United States.
Organization and Structure

The Marine Corps Reserve is organized into several major subordinate commands, each with its own unique role and responsibilities. The Reserve is divided into two main categories: the Selected Marine Corps Reserve (SMCR) and the Individual Ready Reserve (IRR). The SMCR is the primary component of the Reserve, comprising drillable units that train regularly and are prepared to mobilize in support of contingency operations. The IRR, on the other hand, consists of Marines who are not assigned to drillable units but are still subject to recall in times of national emergency.
Major Subordinate Commands
The Marine Corps Reserve is comprised of several major subordinate commands, including:
- 4th Marine Division: Headquartered in New Orleans, Louisiana, this division is responsible for training and readiness of Reserve infantry, artillery, and combat engineer units.
- 4th Marine Aircraft Wing: Based in New Orleans, Louisiana, this wing provides aviation support to the Marine Corps Reserve, with a focus on fighter, attack, and transport aircraft.
- Force Headquarters Group: Located in Norfolk, Virginia, this group provides command and control, communications, and intelligence support to the Marine Corps Reserve.
- Marine Corps Reserve Units: These units are spread across the United States and are organized into various specialties, including infantry, artillery, engineering, and logistics.
