I believe that was the new starter, after they re-released the set with a consistent (and larger) vehicle scale. There has since been several releases for the various theaters, and WotC relased new revised unit stats on PDF as well.

if 2 communist partisans move into the same hex as a tank can that tank then just move out of the hex?
if so can the communist partisans attakc the tank?
The Partisans would get Defensive fire rolls if the tank moved to an adjacent hex… There’s no reason why the tank couldn’t move away though as long as it was on it’s own movement/assault phase- it can’t move away when it isn’t it’s turn (I’m not sure what you’re asking here).
