I was looking through my Dad's stuff and found these badges and was wondering what these badges are. he was drafted into the army during Vietnam and I know the one is an infantry badge I believe but if anyone can give me more information on what these are I would appreciate it. i don't know if they are all military or not. One looks like an elephant and the other like a deer or donkey or something. Thanks. All three badges are shown in the link below. http://imgur.com/a/v2aGn
We have a very handy guide on Military Identifications, which includes badges and the like. I would very much encourage you to peruse through there and there is a good chance you will be able to find some more info on these!
The top one is the Distinctive Unit Insignia for the 3rd Training Brigade, Army Training Center, Fort Polk, LA.
