Can anyone explain to me how you get this achievment on Call of Duty WaW
It seems pretty self explanatory except that I cannot mount a tank.
I have tried jumping on one and can get so far but once it moves I fall off and once I get on a stationary tank there is never anyone there to shoot or once it moves it gets blown up.
So any help would be appreciated.
