Lot of troops are wearing them now as they are more flame resistant than their other uniforms. An no, they are not Airman, the troops in the pics you've seen could be Infantrymen, MPs, etc.

You think these look rediculus an unprofessional? Give your head a shake please, they are at war and are doing what they can to protect their troops. Injuries due to flash burns, fire etc are high over there due to IEDs, vehicles on fire, etc.
