Today descendant elements serve with the New Mexico Army National Guard as the 200th Infantry.

The unit was reorganized 12 September 1896 in the New Mexico Volunteer Militia as the 1st Battalion of Cavalry with headquarters at Santa Fe.

The former 1st Regiment of Infantry was reconstituted 16 July 1919 in the New Mexico National Guard as a separate squadron of cavalry and organized with Troops A and B at Albuquerque and Carlsbad, respectively.

The first entity designated the 200th Coast Artillery Regiment (Antiaircraft) existed from 1921 until 5 September 1927 in the North Carolina National Guard.

Battery G, its only active element, was organized on 5 August 1921 at Raeford, North Carolina and assigned to the IV Corps.

When the deferred list was abandoned, the regiment was withdrawn from the National Guard and demobilized on 5 September 1927.

Redesignated as the 200th Coast Artillery (AA) on 1 July 1940, with the “207th CA” designation being transferred to the converted 107th Infantry Regiment, a New York National Guard unit.

The 200th was doubled in size with draftees to 1,800 men while at Fort Bliss preparing for overseas deployment.

[9] The Arkansas National Guard 206th CA and the 200th competed for deployment to either the Philippines or the Aleutian Islands.

Upon arrival it was assigned to the US Army Forces in the Far East (USAFFE) and ordered to provide air defenses for Clark Field while based at Fort Stotsenburg,[3] although they were not attached to the Philippine Coast Artillery Command, which was primarily a harbor defense command.

At about 0300 hours on 8 December 1941, the 200th went on full alert when the night radio crew picked up commercial broadcasts telling of the Japanese attack on Pearl Harbor, Hawaii.

Headquarters, 200th Antiaircraft Artillery Group, organized and federally recognized 25 September 1947 at Roswell.

[11] The headquarters battery of the 2nd Battalion, reorganized from that of the 200th Antiaircraft Artillery Group, was at Las Cruces.

Equipped with the M42 Duster self-propelled anti-aircraft gun, the battalions served as divisional air defense artillery units of National Guard divisions but were under the administrative control of the 111th Air Defense Artillery Brigade headquarters.

[13][14] The majority of its personnel volunteered for full-time service at McGregor Range, administered by Fort Bliss.

[10] During annual training in 1989, 7th Battalion, 200th ADA, became the first Army reserve component unit to live-fire the Hawk air defense missile.

[27][28] Due to the demanding nature of Patriot training, the 2nd Battalion struggled to fill its ranks: in mid-2003 it had only 202 soldiers out of an authorized strength of 547.

By that point, three Patriot launchers out of fifteen authorized had been delivered to the unit, enough for two of five required batteries.

[34] On 19 December 1941 the 515th Coast Artillery (Antiaircraft) was activated at Fort Stotsenburg as a provisional AAA regiment by the expansion and redesignation of one battalion of the 200th CA.

[36] On 19 December 1941 the regiment was redesignated as the 515th and augmented with about 750 officers and enlisted men of the Philippine Commonwealth Army for training.

Moved from Manila 25 December 1941 (the day before Manila was declared an open city) to defend the withdrawal routes to Bataan, where the unit defended the Cabcaben airfield and other key points until surrendering as part of the Philippine Provisional Coast Artillery Brigade on 9 April 1942.
