Yes, this does help. I'm glad to know what the numbers mean! I know that the motorized Flak served in many different places and that the composition of the regiments was constantly changing, so it becomes difficult to track exactly what he did during his war service. The history of Regiment 16 doesn't tally with his final action at Traben-Trarbach, but I think those last days were quite chaotic. I have his Wehrmacht number, so I'm hoping to be able to get his war record in Germany and perhaps get some information from the Red Cross as well.
My biggest difficulty just now is making sense of the military terminology, abbreviations, etc., used in relation to the organization of the Wehrmacht. I wonder if there is a "Wehrmacht for Dummies" out there that explains all this to the layperson.
Thanks for taking the time to reply to my post.
