Sounds better than getting stuck in the middle of the guys playing OpFor and driving out with one of their vehicles.
I'm more usually tasked with being one of the Opfor elements [BTR70 and 80] and unfortunately swiping vehicles was outside the exercise administrative limits- for one thing, out BTR70s are placarded in Russian, and there's a real opportunity for a leadfoot to get hurt in a BTR, especially on turns.
But I did get to tell the *there I wuz* story about the 7th Army staff who annoyed a German Forester who'd offered them assistance during one of the 7th Army USAREUR exercises, by dismissing him as a *damn fool civilian* despite his 25-some years in the German Army from Wehrmacht to BGS to Bundeswehr...whereupon he *went over to the other side* and hooked up with the OpFor, in this case,. guys from the Tenth Special Forces group....who not only appreciated his knowledghe and assistance, but addressed the former Stabsfeldwebel with the respect due to his rank and assigned him a key position as scout. The SF raid teams had no trouble at all ocating the 7th Army Headquarters TOC, being guided to it by their trusty scout who'd actually been inside it.
It was later determined that due to some oversight, there was no blank ammo suitable for the old K98 rifle he was carrying, which bothered him not at all. He politely avoided actually shooting anyone, but several 7A vehicles lost their tire pressure, and some fairly critical radio equipment failed to operate afterb he was done shootin'.
Though 7th Army Staff was not happy afterward, the 10th Group guys gave him the highest honors they could: one of their own berets, and a standing invitation to the Group's Christmas parties at Bad Toelz.
