?Your e-mail address is "hidden" and, after attempting unsuccessfully for two days to reply to your message, I asked the webmaster, and later, a friend and client, to post this or otherwise get it to you. This may not be of interest but I'll post it anyway:
Stanton lists the battalion as 767th Antiaircraft Artillery (Gun) Battalion (Semimobile). Sawicki as 767th Antiaircraft Artillery (Automatic Weapons) Battalion (Semimobile). Neither mentions anything of a reorganization and/or redesignation at any time in the battalion’s existence. This doesn't happen often but, when it does, I incline toward Sawicki (he devoted almost thirty years to compiling his multi-volume series of unit histories).
The battalion was constituted in the Army of the United States (AUS) 25 February 1943, activated 15 September 1943 at Fort Kobbe, Canal Zone and disbanded 1 February 1946 at Fort Kobbe. The only honor listed is the American Theater Streamer without inscription. The battalion appears to have been assigned to either Pacific Coast Artillery Brigade (later redesignated 76th Antiaircraft Artillery Brigade) or 83rd Antiaircraft Artillery Group. Both were situated at Fort Clayton.
Just prior to the outbreak of the war, due mainly to terrain and other factors, it was determined the greatest threat of attack to the Canal Zone was from the air. Accordingly, a plethora of antiaircraft artillery units was concentrated in the Zone. As the Allies gained air supremacy on all fronts, select battalions, as they were determined to be no longer needed, were inactivated or disbanded altogether to release officers and enlisted personnel for reassignment to other duties. Antiaircraft Artillery - referred to as Air Defense Artillery since the 1970's - has existed, and continues to do so, from its inception to the present.
First, there is not, nor has there ever been "Coastal Artillery." Proper terminology and spelling are crucial - especially when dealing with computers and government employees. You have all the information you need to secure Morning Reports pertaining to his service with Battery C, 767th AAA Battalion. The only problem remaining is dates of service. He can only have joined the 767th on or afterits activation on 15 September 1943. That’s potentially 104 Morning Reports. You still have at least 1 year, 7 months and 26 days (19 January 1942 - 14 September 1943) to account for.
You might try Morning Reports for 15 September through 15 October 1943. If he joined as a new member, there’s a good chance it occurred within that time frame. If you’re lucky enough to locate the MR recording his transfer-in, you can begin to backtrack from there (the MR will state the unit from which he came). You might also request MR’s for 26, 27 and 28 December 1943. One of these should record his transfer from the 767th and, possibly, his destination in the United States.
The 765th and the 767th were activated the same date. It’s possible both battalions were formed with personnel from the 73rd Coast Artillery (Antiaircraft) (Semimobile). The regiment was inactivated 15 September 1943 (less its 2nd Battalion, which consisted of Headquarters & Headquarters Battery, 2nd Battalion and Batteries F and H, all of which were inactivated three months later). He may have likewise joined the 767th from the 73rd. Contact me when you receive the Morning Reports.
733rd Btry Sep = 733rd Battery (Separate), Coast artillery. I’ve been unable to find the slightest reference to it anywhere. I thought perhaps it might be an element of, or somehow associated with, 733th CA Battalion or 733th AAA Battalion but there were no such units either.
