Actually it was implemented at Ft Jackson, SC in 1993 when I was there. Having seen it first hand I think my knowledge of it is more than mythical. However, this was all coming about for the next cycle to pass through and I remember the Drill's talking about the implementation of it. They even had the yellow cards. Also it was right after my cycle that the co-ed things started as well. The drill instructors would actually tell us how cushy the next cycle would have it compared to us.
Amazing. I guess they must have introduced the stress cards for your cycle and then never used them again, considering I attended both BCT and AIT at the same place only last year and never saw a stress card in the entire brigade.

Or heard of one anywhere on post.
