 Fireteam consists of team leader, your automatic rifleman, and then your rifleman. As a team leader, you take the orders from the squad leader and relay them and position your team how you see fit in order to finish your part of the mission. I'm Lance Corporal Flanagan. I'm an automatic rifleman for my team. I carry the IAR. My job is to provide appropriate suppression for my rifle team. I'm Lance Corporal Gill, rifleman in my team. I carry M16, my job. I have another weapon in the fight to engage the enemy. The marine firing is a key part in the fight due to the fact that it is the smallest moving element that can change the tide of the battle.
