The key aspect of our organization is that of closely-knit teams. A rifleman by himself is not nearly as useful as a group of players working as one cohesive unit. Fireteams look out for their own members as well as those of their fellow fireteams. Fireteams are the tip of the infantry spear.
You will find yourself grouped with different players in different missions and your comprehension of this guide is what will allow you to all act as a cohesive and combat-effective group, regardless of who is in your fireteam specifically.
Within each fireteam, buddy teams are formed, typically composed of two members: a leader and a buddy. The leader guides the pair, making decisions and setting the pace, while the buddy supports the leader, covers blind spots, and helps maintain the effectiveness of the team.
