I have a question about the gear color requirements. I have a nice backpack I just got for free from the National Guard. It is a greenish/tan color so I really don't know if it is one or the other. It is solid color and has National Guard written on it, but the stitching is the same color as the rest of the backpack. I just wondered if it would be OK to put gear and stuff in. I wouldn't be taking it into battle, just to hold like extra water, snacks, BBs, etc in. Sorry if this is a stupid question or the the wrong stop, I'm pretty good at that.
