Iran The military of Iran uses a variety of military uniforms, including a solid olive-green pattern. Several other uniforms have also been reserved for parade use, such as a slate grey, a black and white, a beige, a beige on beige, a beige on brown, a beige on green, and an eggshell white-coloured uniform – paired with a matching beret and balaclava. The Iranian military uses several types of camouflage patterns. Three distinct desert camouflage patterns with slightly differing colour palettes and blotch densities have been issued; one for the Islamic Republic of Iran Army, one for the Islamic Revolutionary Guard Corps, and a third pattern used by the tarabaris personnel who repair military cars and trucks.
