limbaugh and a caller agreed that the M1 Abrams is useless in a sandstorm because they can't target anything. what about the Challenger? it must have a similar system

Helpless perhaps, but then again, nobody else can target them in the sandstorm. So, there they sit, they just bide their time, awaiting the sandstorm to end so that they can go about their mission. Like Rummy said.....heat and sand bother both sides equally.
