Hello, Paolo and all others. During the Desert Shield/Desert Storm era we wore many different uniforms, depending on what was available. MOST of all US Armor crew were issued the OD green NOMEX suits, which were our primary uniforms while in our vehicles. This was due to the fire resistant properties of NOMEX. Also, like Louis mentioned, we often wore the (terribly uncomfortable and filthy and HOT in the desert) MOPP suits. (MOPP = Mission Oriented Protective Posture) They were pretty universally hated because they were made of a special chemically infused cloth with a black thick rubber foam lining that was full of charcoal dust - which got all over all your clothes and skin. However, when we got off the tanks, we wore the "Chocolate Chip Cookie" Pattern of BDUs. (Sorry, I forget the correct name, but Louis kindly posted a picture.) Since there weren't enough desert camo uniforms for all soldiers to have enough, the Woodland Camouflage uniforms were also worn. We wore our standard issue black leather boots until early February, when some of the front line units were issued the Desert Tan nylon upper, brown suede leather lower boots. I personally wore a pair of Vietnam Jungle boots (green nylon upper, black leather lower) until I got my pair of Desert Tan boots, at which time I buried the jungle boots in Saudi sand! They were old and beginning to fall apart! There was one more type of uniform worn by a few soldiers. Some of the troops who were behind the lines (waaaaay behind the lines) had the newest desert camouflage uniform. I will try to post a photo.
These troops far from the front line all had the latest uniforms and boots. Isn't that always the way it is!?!
Anyway, I hope this helps. To sum it up, when my Platoon of M1A1 (HA) tanks went into Iraq, my troops wore the OD Green NOMEX coveralls, black or tan boots, and we had on the MOPP suits, which were OD green over our NOMEX. After the fear of chemical attack was over, we were back to our NOMEX. Off the tank, we wore the Desert camo BDU. (Battle Dress Uniform) Years later, I understand that Armor troops were issued Desert Tan NOMEX as well as Desert Camo MOPP suits and digital camo, but those didn't appear until after Desert Storm.
Keep your ammo dry!

Below is the newer Desert Camo BDUs that some wore in ODS but I never had.
