52nd Air Defense Artillery Regiment

The 52nd Air Defense Artillery Regiment is an air defense artillery regiment of the United States Army first organized in 1917 as a railway gun unit of the Coast Artillery Corps. It was first designated as the 7th Provisional Regiment (Coast Artillery Corps), then the 52nd Artillery Regiment (Coast Artillery Corps), and then the 52nd Coast Artillery Regiment. It continued in that role unit 1943, when the regiment was broken into separate battalions, and in the following year the units were reorganized and redesignated as field artillery units. The Combat Arms Regimental System revived the regiment, in name only as the 52nd Artillery Regiment, through regimental affiliation for battalions without a command relationship to each other. The Headquarters and Headquarters Battery of the regiment was reactivated under the 52nd Artillery Group in 1950. The unit was finally redesignated as the 52nd Air Defense Artillery Regiment in 1971 after being consolidated with other units such as the 52nd Field Artillery Battalion. The United States Army Regimental System introduced regimental affiliation to individual soldiers.
