213th Air Defense Artillery Regiment

The 213th Air Defense Artillery is a regiment in the Pennsylvania Army National Guard.

The regiment appears to have been established as an Air Defense Artillery Branch unit in 1989–90, according to The Institute of Heraldry insignia data. The Reading Eagle of August 31, 1989, advertised for personnel to join Battery B of the 1st Battalion, a 'new Army National Guard unit'.

The first appearance of the number "213" was with a Coast Artillery Corps anti-aircraft regiment first established on 1 May 1922. Major General John E. Stevens led the creation of the 1st Battalion, 213th ADA from the previous 165th Military Police Battalion, with the new unit seemingly established in August 1989.

By October 1, 1997, it was part of the 28th Infantry Division.
