idea#1
maybe different classes should have different colors. like spartans have the khaki/blue/black-silver combo while reg marines have pure khaki, ODST's have pure silver or black so on and so forth.....get my drift?
idea#2
like i was saying before, do the multi color one for the overall 405th on the left shoulder because it has priority over other patches and then on the right shoulder have another patch signifying if you are a helljumper, ODST, Marine, Spartan, Cqb, etc.
