Practice day should focus on strengthening teamwork and reinforce the importance of working together. Front players will learn how to work with back players if they only have 10 paintballs and 30 seconds to shoot a target while someone tries to keep their head behind cover. Two players with 10 paintballs each will have to work together to take out one player with a full hopper. Tactics are planned moves or plays that rely on players working together. Just like technique comes before teamwork, tactics are lost on a team that can't work together.
Tactics rely on everyone knowing what their role is in the team.
Tactics start when you walk the field. Even if you have a brain's trust, it is still important to involve everyone in the formulation of tactics. Everyone needs to know his or her role and feel a part of the game plan. Practice day should involve reinforcing the thinking side of Paintball and how to out-smart another team. Practicing plays will make it easier to execute them on the day.
