Did any National Guard units get activated to serve in Southeast Asia ( Vietnam)?

Question

If so did the State from where activated loose control placing it in the hands of the DOD?

Has the format changed when the draft ended?

Answer 1

Yes.

When activated for federal service, NG troops are temporarily not under the control of their states.

Answer 2

Quite a few units of both Air and Army National Guard were called up for duty in the former Republic of Vietnam.  Here in New Hampshire I know of the veterans of the 3rd Battalion 197th Field Artillery who were deployed to Vietnam from September 30, 1968 to September 2, 1969.  They were M110 8 inch Self Propelled Artillery that converted to M107 175mm ('Long Tom') Self Propelled Artillery while in Vietnam.  They served in the II Field Force Vietnam which was the largest U.S. combat unit in the field servicing as general support artillery for some 16 to 18 Army Divisions.

Yes, in such circumstances the state which those National Guard Troops come from looses control over them for the period of their federal service.  The same is true for the National Guard units today that are deployed in federal missions.

These deployments are in no way related to the Selective Service Act or Draft; When you join the National Guard of any state you should be fully aware that you serve as a Reserve to the U.S. Army and are subject to federal activation should the need arise.

Answer 3

Over 50 thousand members of the National Guard and Air National Guard served in the Indochinese Theater of Operations during Vietnam. One of the most decorated units was an artillery outfit from the West Virginia National Guard.

The Air National Guard participated under the Palace Alert program. One of those who volunteered was First Lieutenant George Walker Bush of the Texas National Guard. But, the aircraft type he had trained and qualified in was obsolete at the point in time.

The format of federalizing troops from the National Guard has not changed since the First World War.
