Teamwork will give you the added extra, the slight edge that will lead you to victory. If you’re a squad leader, and if you don’t have a mic, you won’t be able to communicate well, please get a mic. You have to talk to your squad leaders often about where to go, where the enemy is, where to mark arty, how the situation is, etc.
Were you just running through the jungle trying to run away from the AC-47 and went to yourself, “Lemme stop and check the chat.” People who use typing to communicate are fools. This role requires a lot of communication and coordination, which is the glue of teamwork. If you are the commander, and you don’t have a mic, please get off and let someone else do it. Don’t be in a position of leadership if you have no mic.
