uspi7 reminds me a bit of those pic I saw standing on top of their cars waiting for a rescue boat during the floods.
Not all AFV's have good visiblity for the drivers. In order to give him more protection, the driver's position is lowered and sloped more. This reduces visibility in nearby areas. Other times ground that looks safe sometimes is not. When off-roading, I have been stuck in places that you would have sworn we could drive over and went through muck that we tought we couldn't.
ahh, but the point is you saw the muck and thought you would never get through but still went ahead anyway! you can see the driver thinking, it's only a small puddl and we are water proof up 4 feet so it should be OK anyway. Of course the lack of water proofing at 4 foot is the open hatch that the guy is sticking his head through so they get a full soaking including their seat, shoes and butties. FNG
I thought tanks were invented in WW1 because every other kind of vehicle, or gun got bogged in the mud. Now they will have to invent another kind of AFV.
Does the Abrams have escape hatches underneath? (doesn't look like it) if not then the crew may still be in the tank in the last two pics. same goes for the leopard.
