I'm leaning towards a M163, nothing terribly radical, but I've always liked that vehicle.
My storyline is roughly that prior to the Medak Pocket incident , Canadian forces decided it needed some more presence in the battlefield, not having the time to prep and ship tanks from Canada, M163s were loaned from the US. Quickly painted the vehicles were slipped into the front line without either Serb or Croatian forces noticing but finding out in a hurry that the Canadians had a nasty surprise for
anyone who wanted to start something.....something like that.
I think I'll write an after action report or something just to add to the fun.
