You null and voided your whole statement.
Army. The United States Army is the main ground-force of the United States. The Army's main function is to protect and defend the United States (and its interests) by way of ground troops, armor (tanks), artillery, attack helicopters, tactical nuclear weapons, etc. The Army is the oldest U.S. Military service, officially established by the Continental Congress on June 14, 1775
Marine Corps. The Marines are often referred to as the "Infantry of the Navy." Marines specialize in
amphibious operations. In other words, their primary specialty is to assault, capture, and control "beach heads," which then provide a route to attack the enemy from almost any direction. The Marines were officially established on 10 November 1775
And the big picture is...Your comparing a couple of Jabs to knockout blows...
also it seems as if you missed the concept of The Marines having a Reserve....Just like the Navy.....And the Army/AF having reserves and National guard......But forgot about the active duty component that lets me know that your going off of hersy or something you've read.
so how long were you in the Marines? We're you in the military at all?
