Like I said before paintball has some good parts but everyone gets complacent when playing it since it is a game. When the real shots happen I am not sure how much it will help and when there is a friend shot in front of you it will not be much help because it is real and not paintball. Some of the tactics are good but a little on the fast side since it is paintball and not bullets coming at you.
I think that if used right which I saw four guys in the woods do, where they did two man team. They did it slow and in real life tactics. Paintball would work that way. But it is no good in the playgrounds that you go to play paintball, not real.
