Description

The United States Marine Corps. Motto: Semper Fi. The United States Marine Corps is known to have the worlds finest fighting force, and to conduct operations world wide to keep peace and conflicts from causing destruction and bringing terror. The United States Marine Corps is the strictest and has the most brutal boot camp training at Parris Island or San Diego Marine Corps Recruit Depot. The United States Marine Corps is also known for its amphibious assaults and connecting sea, to land, which is how they earn their amphibious reputation.

Membership history

Growth

2 measurements spanning 63 days, net -1. Dots are measurements; the straight line between them is drawn to join them, not to claim we know the path taken in between — snapshots are recorded only when a count changes, so gaps mean “no change observed”, never “interpolated”. The vertical axis spans 13–14 and does not start at zero.
