Medium infantry refers to ground troops, less heavily armed and armored than
heavy infantry, but more so than
light infantry. In the modern age, medium infantry has largely been replaced by
mechanized infantry.In the
US Marine Corps, medium infantry battalions are comprised of three medium infantry companies, which are made up of three medium infantry platoons and an assault gun platoon. They are armed with
LAV 25 wheeled armored personnel carriers and
Javelin ATGMs. The US Army's new
Stryker brigades fill a role between light and heavy infantry, and are essentially medium infantry. When equipped with the
Stryker mobile gun system, these units have much heavier firepower than traditional light infantry, but lack the
M2 Bradleys and
M1 Abrams that heavy infantry brigades use.
