Marine (military)
The United States Marine Corps (USMC) is the largest marine force in the world, responsible for many United States expeditionary operations.  They were created in 1775 to guard naval vessels during the American Revolutionary War.  While the USMC is a component part of the Department of the Navy in the military command structure, it is a military branch separate from the United States Navy.  The USMC also provides security guards at U.S. diplomatic posts throughout the world.  They also provide helicopter transportation for the President of the United States aboard Marine 1. Their motto is Semper Fidelis, "always faithful".  And mascot Chesty the Bulldog after receiving another title from the Germans after the battle of Belleau Wood "Teufelshunde" meaning Devil Dogs.
