not the way EA does it. spearhead is laggy enough as it is, can you imagine how much worse it would be with tanks and jeeps rolling all over the place? plus the maps aren't really made for them. but if they found a way to do it it would be pretty sweet, it would be like BF1942 but more fun.

of course then you would run into "omg tank faggot" "jeep n00b" "omfg auto-tank hack"
