The “ 3rd U.S. Infantry Regiment (The Old Guard) The 3d United States Infantry Regiment is a regiment of the United States Army. It currently has three active battalions, and is readily identified by its nickname, The Old Guard, as well as Escort to the President.
The regimental motto is Noli Me Tangere (from Latin: – “Touch Me Not”).
The Third United States Infantry Regiment, also known as “The Old Guard,” is known today for the ceremonial duties it performs at military funerals, Presidential ceremonies, and guarding the Tomb of the Unknown Soldier at Arlington National Cemetery. This is the oldest unit in the United States Army. It was organized as the First American Regiment in 1784. After the War of 1812, it was consolidated with other regiments to form the Third U.S. Infantry, based on the seniority of the then regimental commanders. The Battle of Gettysburg was not the unit’s final moment.
