1) US Army – “This We’ll Defend”

This famous motto dates back to the Revolutionary War. When the Continental Army was formed in 1775, it adopted it as its official motto. Therefore, it is the oldest motto in the U.S. military. 

2) US Marine Corps – “Semper Fidelis”

The Marine Corps motto was adopted in 1883 by Commandant of the Marine Corps Colonel Charles Grymes McCawley. Marines have now shortened it to “Semper Fi” which means always faithful. It is also used by Marines to address each other.
