Artillery - Officer - Lieutenant Colonel T-Shirt

In the United States Army, Air Force, and Marine Corps, a lieutenant colonel is a field grade military officer rank just above the rank of major and just below the rank of colonel. It is equivalent to the rank of commander in the other uniformed services. The rank of lieutenant colonel was first created during the Revolutionary War, when the position was held by aides to Regiment Colonels, and was sometimes known as "Lieutenant to the Colonel." The rank of Lieutenant Colonel had existed in the British Army since at least the 16th century.
