Armored D7 Caterpillar tractors were used in Iraq to tear down buildings hiding insurgents. I wonder to what extent they were affected by dust.

Carl Szabelski AT list member and tank knowledge resource <szabelski at wildblue.net>; <snip> Working in places like Iraq, especially in wide open areas, is really difficult to do. Some of the sand there is so fine that the slightest breeze will deposit a coating on everything. It’s finer than talc and would get into everything. Not a good thing for precision made bearings and other highly sensitive parts. Even trying to do repairs in tents and huts does not help.<snip>
