No.
The mortar team set is in post-VN uniforms (other than the LBE are all buckled, something mortar crews did not much do in that era.
True VN US uniforms would not work with their diagonal pockets.
The "weight" of the uniforms would be a good match, though.
Just have to make sure none of the figures are in body armor, as I'm not sure either side wore that during the Iran-Iraqi war.
I might have used modern Italian helmets for Iraqi, but soviet ones would be cloes enough (and easier to come by).
Iraqis have a mix of sand and OD uniform parts. They have a semi-unique item that looks a bit like a hoodie crossed with a windbreaker.
