Marine vs. Army

Marine (adjective) describes a member of the United States Marine Corps (a small branch of the Navy) trained to be highly mobile and to attack from the water, deployed overseas by naval forces.

Army (noun) describes a soldier in the United States Army, whose mandate is providing for the defense of the United States in ways including operations in foreign nations hostile to the United States.

*Tip/Hint: Marines fight battles, and Army members fight wars. The Marines are a smaller unit of defense, and the Army is a larger and foremost unit of defense.
