Hey, ask your nephew sometime about Hydration Formations! LOL!
The guy that I talked to said that as far as he knew, the "stress card" had been done away with. However, he has been out of boot camp for quite some time now and isn't sure that they don't still do it. He did say that he was in a training facility and a guy pulled one on him once. He is checking around to see if he knows anybody that kept one, and asked to have me call back in a few days for a copy of one (if he can find one).
Don't believe me? Call your local Army Recruiter and ask. Phone book, under "Recruiter".
