I was wondering if anyone knows what I have to do to get credit for the ammo 62 hazmat class if took.
Assuming you took this while in the service, it, plus all of your training can be used as college credit. If it was the army look up AARTS transcripts. Here is a link it looks like they have unified all services. The security token is out of date so if this isn't the right link someone can post it or you can do your own search. https://jst.doded.mil/smart/signIn.do
If you took it as a civilian, set up an ACE credit account and add it to your courses taken in the registry and transcript system. When I did it took a few days for the Defense Ammo School to verify completion and ACE added the credit recommendation to my transcript.
