The 12th Cavalry Regiment Distinctive Insignia are hallmarked by Bailey, Bank & Biddle Company (BB&B Bronze).  They are clearly illustrated in BB&B Company products catalog as item 29396 - Regimental Coat of Arms, 12th Cavalry.

Detail pixs of the coats insignia.  The collar brass indicating 12th Cavalry Regiment and a rather unique two piece Type II Discs that wasn't circulating as readily as those singular stamped types like the U.S. 12 disc.    

Here's a total unrelated 1st Cavalry Division, 1st Cavalry Brigade, 1st Cavalry Regiment (12th Cavalry Regiment) uniform that I just plucked out of storage.  Together with the colorized studio photo make for a great display.

Yes, that is correct, Doyler. I should have been more specific-when I was wondering about the Marine Corps I was thinking more of an aviation support type unit-although most of those abbreviations start with the letter "M" like MABS, MACTU, MACS, MWSG, MWSS, MAMS, MASS, MWCS, WERS, TACC, etc.

It been a while since I've added anything meaningful to my thread so here's some stuff to share.  The colorized portrait isn't one of those digital enhanced jobbies of today's technology but a true photography artisan that actually tinted the former B&W studio portrait of this 12th Cavalry HQ Troop trooper.  Yes, this was one of two colorized images of the same solidier that I illustrated my ASMIC article with.  I managed to make a negotiatable trade with Mitch for the two portrait photos. 

That is an interesting item, I have not seen another to date, will put it on my search list.  Thanks for posting.  Cheers, Armygas

Navy squadrons typical start with the V designation for lighter than air as VF is an air Fighter  (hence the F) group, VP (Patrol Squadron etc and Marines use VM or VMF as VM is Marine designation and F for fighter. 

Lot of speculation. A derelict us tank in France, Italy, or Germany, awaiting recovery, probably soon after the war, sensitive equipment removed earlier by ordnance unit, sitting on a road travelled by the American forces, a GInea ting a souvenir photo.

A quick glance a Sherman, it also has an Invasion star on top of the turret.
