Ah, just missed you- I started high school in '85.
The marathon Graf rotation I'm thinking of was last quarter '90. That's when I went to Vilseck for this training.
They did a great job, too. All the folks who wore the "7 steps of hell" patch did alot of good things.
Watch out for the feed tray on the DsHKM - I saw two guys lose a finger, trying to feed it like an M-60.
