Iraqi used wz 50 helmet
During the Iran-Iraq War, the Polish WZ 50 helmet was heavily used by the Iraqi military before the M80 came into service. Even then, the WZ 50 was seen in the Iran-Iraq War all the way up to OIF. Arguably, Polish helmets are the most commonly encountered steel helmets that Iraq used. Please note that other countries used the Polish WZ 50 and not just Iraq.
This particular helmet was captured in Desert Storm. Most of these helmets that were a bringback exhibit lots of wear, especially from the sun, and have lots of sand in it. This one's liner has become petrified from the heat. Steel helmets like this one were usually issued to artillery crews.
