For some reason I've always like the Stugs. Maybe because they are ugly. I like the M3 medium for the same reasons I think. I also find the early war vehicles more interesting again perhaps because they all have serious flaws of one sort or another.
That remindes me Tomcat, the other day I was messing around on Combat Flight simulator 3, and I landed a B-25 on a road and shot up a convoy that passed. That was fun.
