5th Air Defense Artillery Regiment

The 5th Air Defense Artillery Regiment is an air defense artillery regiment of the United States Army first formed in 1861 as the 5th Regiment of Artillery.

Lineage
On 4 May 1861, in conformity with the proclamation of the President, a new regiment of 12 batteries was added to the artillery arm of service and became known as the Fifth of the series.

Congress confirmed this act of the President, 12 July (approved 29 July) of the same year, but all appointments dated from 14 May.

Differing in organization from the older regiments, the new one comprised only field batteries, being in this regard the first entire regiment so equipped in the Regular Army. But it must not be inferred that the Fifth was designated by law as a light artillery regiment. "Nowhere in the act of 29 July do the words 'field or light artillery' occur, nevertheless, the batteries received the personnel belonging to field-artillery only. This, together with the other fact of the mounting, equipping and sending out as field artillery all the batteries, does not leave in doubt that Congress intended the Fifth to be a field artillery regiment." 
 * Regiment broken up 13 February 1901 and its elements reorganized and redesignated as separate numbered companies and batteries of Artillery Corps
