while messing around offline i noticed that if you shoot the deck of the CV with the turret mg there are splashes that look like you shot the water
you can kill you self in the LVT 4 if shoot low enough and the barrel on the M8 glitches through the gunner postion
and it seems the T34 85 the tracks move when the tank is not in motion
EDIT: it seems it only happens when your on a CV and it happens to all the tanks
