In order to soundly defeat your statement, I searched diligently...and found out they used BOTH terms back then, and I owe you an apology!!
When I was in, the term MEB was not used at all, MAB was, MAU, MAB, MAF. That was changed to MEU, MEB, and MEF just before Deset One
I owe you a beer! :)
No apology needed - just glad I didn’t get nuked
They don’t believe my Vietnam story too lol:
