Calling

Calling in TF2 is communicating with your team to relay information so that everyone knows what's going on. Calling is arguably the most important skill that a team can have, next to deathmatch skill and positioning.

Main Caller

The main caller is the backbone of any team, be it a Highlander or 6v6 team. It is the job of the main caller to communicate with the entire team, informing them when and how pushes, retreats and various other plays are to be carried out. It is essential that the main caller is communicates clearly and concisely so actions are carried out as soon as possible. Teams which often fail to listen and react to the main caller generally fall apart due to a lack of focus on their enemies, positioning and the game as a whole.
