What's After Boot™: Marine Corps Weapon Systems

While attending School of Infantry (SOI), your Marine will become acquainted with a variety of different weapons and weapon systems. This is a crucial component of Marine Corps training. Every Marine is a rifleman and any Marine may find him or herself faced with combat operations, whether he or she is an infantry Marine or not. Building combat-ready Marines (see video below) is absolutely paramount to the continued success of the Marine Corps. The first step in doing so is becoming familiar with Marine Corps weapons and tactics.

While attending SOI, Marines will receive training with the following weapons:

• M136 AT4
• M16A2/M16A4
• M203 Grenade Launcher
• M240 Machine Gun
• M249 Squad Automatic Weapon (SAW)
• M2 .50 Cal Machine Gun
• MK "Mark" 19
