Lead, Follow, Get Out of My Way
If you're going to play a game or anything that involves a group working as a team, there's some basic fundamental understanding of roles that everyone accepts. This basic understanding can be seen in any sport, any team activity, and pretty much every organization where there are people working toward a common goal.
I'll lay it out for you, purely and simply. Remember, these roles are sometimes assigned, but sometimes through the natural pecking order of people's personalities, abilities, etc, they fall into the roles by themselves.
The Leader: Even if there is no designated leader, a leader type is always present. He is the one that guides the rest of the group in what he thinks is the best. In order to move things forward, he will take the ropes if nobody else comes to a decision or works together. Leadership positions tend to change due to circumstances. In terms of something tactical like paintballing, someone may be a better leader at capture the flag while another is a better leader at search and destroy. Some leaders are assholes and just tell other people what to do, other leaders get stuck with it because there is nobody else filling the role and nothing is getting accomplished. You'll understand as the other roles are defined.
The Neutral Follower: This is the type where he doesn't like assuming command. These types are willing to do anything and will readily take on a cause without complaint--so long as they aren't the ones making the decisions. They are usually experienced and organized in terms of getting done what they're told to get done. They make desicions if they must, but they usually don't act out on their own.
The Indecisive Follower: Unlike the neutral follower, this person just doesn't have a solid concept of what's going on. He usually ends up just doing what everyone else is doing and if he's assigned to do something, he'll reluctantly do so. He'd rather just sit and see what happens. This type of person is usually really inexperienced and is afraid of making mistakes.
The Willing Supporter: This is an experienced person who has a solid understanding of what is going on and is capable of doing things on his own. He agrees with the Leader only because he knows that it's one of the possibilities that the supporter himself has thought of, so he's ok with the fact that someone else said it first. He is also comfortable in taking a secondary role for various reasons including perhaps the fact that he doesn't like the added responsibility of taking charge. He'll fulfill his role, usually doing an excellent job. If the leader were to ever be in a position where he is unable to lead, this type usually becomes the secondary leader since he can read what is happening and assume the role as the leader would have.
The Devil's Advocate: This is the person who knows what he's doing, thinks he knows what he's doing, or just wants to cause trouble. He's the one who could have been leader, but didn't because he either couldn't fulfil the role, couldn't control the other members, or just plain pussied out of it. But in some cases, that doesn't mean that he isn't someone who could make perfectly acceptable decisions. But since he's not the leader, he instead becomes bitter and tries to actually distrupt the flow of the rest of the group, voluntarily or involuntarily. Even if everyone agrees to do what the leader says, he'll take a stand for no apparent reason and try to change things. This kind of personality type usually inspires irrational decisions that could possibly deteriorate the goals of the group, the direction of the group, or possibly the group itself. He's also most willing to strike out by himself in order to prove a point or just not deal with what he considers incompetency among the rest of the group.
As you can see, a team full of followers by itself cannot function properly, but with a leader, a lot can be accomplished. Usually a team will have various types of followers and a couple willing supporters. If you're unlucky, you'll have a Devil's Advocate. Roles are interchangable. An Indecisive Follower upon becoming more experienced or comfortable in the activity may become a Willing Follower. A Willing Follower may regress to a Neutral Follower if things aren't going as he'd like them to or digress to a Devil's Advocate if he deems his choices were better suited. A devil's advocate may assume the leader role if the current leader makes too many mistakes and sways the rest of the group to try a completely different approach. You get the picture.
This role system can be applied to a multitude of activities including things like football, paintballing, multiplaying online shooters, and just about anything that has a tactical or strategic element. Not only that, it can also be applied to events like organizing a trip or a party.
So lead, follow, support, and if you wanna bitch, do something about it or shut the fuck up.
