This uniform is in the BDU (Battle Dress Uniform) cut, and is in the Tiger Stripe pattern. The pattern grew out of the Vietnam conflict, though no one is really sure who is responsible for its creation. The BDU cut is extremely comfortable, and is one of the most popular available.
It was adopted by the South Vietnamese Marines, and even by many US Military personnel (though that was on commission, due to the difference in leg length etc). The pattern proved exceptionally effective for the Vietnam conflict, and thanks to its iconic look it has stayed in favour with airsofters.
Even now it is still in favour with the the some US Special Forces units in Afghanistan thanks to its effectiveness in the environment
