With your team ready you can dominate. Now have fun!
The first step to making an airsoft team is to find good people. So, you have airsoft wars with your friends. You then pick out some really good players you notice. Once you do pick the players, practice for any competition that comes up. When that competition happens, your team will play pretty decent. Now don't blame me if you don't win but it will get yourself pretty far. (If you get good people that is.) If you notice that someone is good in one category, put them to work at it in an airsoft war. Also, I don't know why the picture is small.
Step 1: Practicing
Now I'm not just posting this to tell you to get good people. You need to practice, practice, practice, and......practice. I would do about 1 a week or so. You just need to see that your team is improving. If not, practice more. (I doubt that would happen.) But just saying. If their is a certain member that needs to improve, put your main focus on him/her :P and try to give him/her tips on how to improve or they can also practice more if it comes down to the decision.
