Why hasnt that happened to any Abrams yet? You could do the same thing to the Abrams, Leopard, Leclerc, Merkava, Challenger, etc.
Because there hasn't been a matched tank battle in what, 60 years?
Also, for the bridges, use AVLBs, and if its a river use pontoons or ferrys or dive.
HAHAHAHA. No.
It's the muddy gulches, and the big rivers that get you. Look at the bridges in Iraq, and the paths of advance and you will see just how important bridges are. AVLBs have weight limits you know. And the areas around where you put them can't be too soft ground or they will sink in.
