This is my ideas for my marine militia sniper outfit from Contact Harvest's militia but with an extra gillie suit jacket and either a boonie hat or helmet or MICH helmet.
all of the guys in the military on the 405th would know what MICH type helmets are
I am not very sure other than it is/was the standard ballistic helmet for the U.S. armed forces that is the helmet that was introduced in the first PERSIAN GULF WAR?
