well we dont use paintballs we use plastic bbs and they dont really hurt that bad unless you get shot on the skin and those can sting a bit. as for knowing if u hit someone we jus trust that the people we are playin agianst will tell u when they get hit
Airsoft bb's are not intended to leave a mark (paint or otherwise) and are composed of .2g or .25g of plastic.
