Marine Corps Weapon Systems: M16A2/M16A4

The M16A2 service rifle is the standard-issue weapon of the Marine Corps. Marines first become familiar with this weapon while at boot camp, where they are taught everything about the weapon. Marines learn it and they love it. After all, the Marine Corps' motto is "every Marine a rifleman." While in boot camp, recruits receive basic instruction and are taught to fire this weapon. Later, at the School of Infantry (SOI), they further master their rifle skills and combat marksmanship. Upon graduation from SOI, Marines will be assigned to a unit and report to their Permanent Duty Station (PDS), where they are issued their very own M16A2 that will be in their care for the next few years.
