Trick Runner: This is the guy who carries the ball and is responsible for scoring. It's also his job to function as a quarterback for the team and make callouts for his teammates. A vocal runner is usually much more successful than one who is not.
Tanks: A tanks job is really quite simple: plow through everything in their way and create a path for the runner. Most tanks prefer to use their hammer the majority of the time, however there are some tanks that rely on the sword. They would be referred to as Sword Tanks. Tanks are also responsible for keeping the opposing team's defenders busy, causing them to lose track of the ball.
Hybrids: A Hybrid is basically a jack of all trades. They're capable of doing whatever is necessary to get the job done, whether it be tanking, running or defending. Many teams now assemble themselves primarily with Hybrids, allowing them to field much more versatile line-ups.
Defenders: A defender's number one job is to keep track of the opposing team's runner and do whatever it takes to not allow them to score. These will be the players who stay back behind their teammates, shadow the opposing team's runner, make callouts and sniff out launches.
