Infantry is the fundamental base of the Marine Corps. Comprised of four Marines, the fireteam’s small size dictates infantry tactics, and is vital to the flexibility and maneuverability of a squad. It’s led by a fireteam leader, whose understanding of small-unit tactics is required for the team’s proficiency.
In the video below, the fundamental “leap frog” principle is demonstrated by 3rd Battalion, 2nd Marine Regiment in squad-level attack exercises at Camp Lejeune, North Carolina. The point of bounding is to overwhelm the enemy with suppressive firepower while maneuvering. Working in four-man groups, Marines are taught to say, “I’m up, they see me, I’m down,” to bum-rush an objective. Watch and learn how a Marine fireteam advances on an objective.
