Ricky always wears his gasmask, as well as his desert gear. He carries a knife, and everything he wears is desert camo, even if he isn't in the desert. His gasmask has full line of sight and does not distort his vision so he is much better with his aim. Beyond his suit and gas mask, no one has seen what he looks like underneath, and he wants to keep it that way, as well as why he wears it in the first place.
