Sorry.
Well, rejoice, your Soviet Tiger unit had more vehicle than mine.
Flames of War has a "Decoy" rule for "Spetsnaz" for Bagration (although the latter didn't exist by then, but there were special scouts performing that kind of tasks) using captured half-tracks and equipment to close on German position under a false flag.
I know captured SdKfz 250 or 251 were used by the Soviets when possible, but I've always wondered if there was some truth behind that?
Truth to the infiltration tactics? I can recall reading about it in the past, but I'm not sure if it was the Soviets doing it. I think the East Germans had a special panzer battalion with M48s and M113s captured in Vietnam, and of course Skorzeny's Panzer Brigade 150. Soviets were kind of famous for their infiltration tactics, so I wouldn't put it past them. Using captured vehicles under a false flag, though, may have been a local tactic rather than a widespread practice.
