A Fireteam is a small squad composed of two to three players, intended to make combating enemies and completing tasks easier than when playing solo. Fireteams are able to take on more dangerous enemies and tasks than solo players, and may be rewarded with greater loot and experience as a result.
Fireteams may be composed of multiple different classes.
Bungie highlights the importance of Fireteams in Destiny as being “your finest weapons” in combat. Working together to bring down powerful enemies is recommended, but is not necessarily mandatory when in a Fireteam, as players who wish to operate independent of their teammates can still be an effective member of a team; for example, snipers can watch over their teammates from afar.
Every member of a Fireteam is important.
Of all the firepower you’ll bring with you from the Tower, the Guardians by your side will be your finest weapons. I’ve seen heroes rescue each other from certain oblivion more times than I can count. There are no tourists in the world of Destiny. Every player of this game changes the action, be they hardcore or brand new to the triggers.
The Fireteam that fights together thrives together.
There is a difference between playing with someone and simply playing near them. When Fireteams work as a real team, they profit. Their abilities complement each other. Their bravery enhances each other. If you can stay close to your Fireteam, you’ll be pretty deadly when you find yourselves backed into the same corner.
You must sometimes divide to conquer.
While it makes sense to combine your forces, you won’t always want to stand right next to each other. Many of your opponents won’t go down with one shot – or even one reload. You’ll want to goad them into fighting a two-front war. Take turns drawing their fire while your ally delivers the pain. It’s like that old saying: Sometimes, teamwork is just giving them more people to shoot at.
