Marine Corps

The U.S. Marine Corps is trained, organized and equipped for offensive amphibious employment as a "force in readiness". Its primary specialty is to assault, capture and control beach heads, which then provide a route to attack the enemy from almost any direction. The Marine Corps also conducts operations on land and in the air in connection with naval campaigns; and is responsible for providing detachments for service aboard certain types of naval vessels, as well as security forces for naval shore installations and U.S. diplomatic missions in foreign countries. The Marines are often the first to fight entering combat zones very early in a battle, often prior to other services.
