Honestly looks more like a Roland SAM carrier of some sort. There were a number of truck mountings, but this one doesn't look familiar.
Something similar to the German
FlaRakRad, just on a different chassis.
My copy of Jane's Weapon Systems 1986-87 lists Roland in Iraqi inventory, which I also realize is in the default OOB. Roland being French/German could easily have led to the confusion with Crotale.
