Hi,I posted this information back in March so not sure if you saw it or not.
If you contact this person, he may have a roster of each of the Batteries that was in the 436 AAA.From my own success in researching the 778th AAA, there were Medics assigned to the Battalion.It seems they were associated with the HQ Battery but I believe they were dispersed some of them among the Batteries.
This is the 436th Association contact. I hope it helps you.
436th AAA AW Bn (WWII) Mr. Lewis C Young - Age about 86 6315 S Boston St Fort Smith, AR 72903-4929 (479) 484-7607
