I really like this modified belt 

That's really interesting.  I've gone through Sawicki's Tank Battalions and Stanton's Order of Battle and can't find anything armor related with 328.  And just out of curiousity I looked at the 2nd AD for anything 38 related and came up empty.  

of course

And, not only used for pilots (per another response). Used to refer to any aviation personnel on flight status who are currently physically unable to fly.  

Thanks Mikie !! I have a few of these hard hats. Whenever I run across one of these I will usually buy it. 😂    

That’s a great looking hard hat!! Thanks for posting and sharing your helmet here!!   Chris

A bit late to this… but the most likely and WAY less cool answer is that this officer reused a BDU from their time as a cadet at the USAF academy.    There was a period of time where cadets wore a class number (exampe: a “98” for the class of 1998) above the name tape. So the two missing patches would have been a class number and a USAFA patch on the pocket. 

I'm new to the forum, but not to U.S. history! I mainly focus on the colonial era, both world wars, and a bit of the cold war. I've been (trying to haha) collecting pre 20th century books (right now I have a US history book from 1886 and a US Senate Report of Committees book for the first session of the 48th Congress Vol. 5 from 1883-84). Recently I picked up a WW2 era EM cap that I'd like to share and learn more about.
