The buddy team concept ensures that every person has at least one other person looking out for them at all times. It simply means that you always move with, watch out for, and fight with at least one other person at your side. - Stick with your buddies. When they move, you should be with them. Together you are far more effective than apart. - Communicate with your buddies. If it's important, let them know. If you're moving, say so, so that they can know to cover you. Good communication keeps everyone working together and aware of each other's status. - Cover your buddies. Cue off of your buddy's movement, sector of observation, and so forth. If they're watching one way, cover the other. If they're going to cross a danger area (such as a street), cover them as they move. - Maintain accountability of your buddy. When you change positions, make sure they come with you - leaving a wounded buddy behind in haste is an unpleasant realization to have. - Pull your buddy out of the fight if they go down. If you are incapacitated, you can count on your buddy to come to your aid. Likewise, if your buddy is incapacitated, you know to step forward and do your part to save him, or contribute towards someone else, such as the medic, saving him. This may entail dragging him out of a danger area, carrying him to a medic, using smoke to conceal his position, or simply killing whoever tried to kill him.Remember that you are no good to him dead - if the tactical situation does not allow you to immediately help him, your task is to help make the situation more favorable - typically accomplished by killing the enemy, or coordinating with others to help kill or suppress the enemy. If your buddy is hit, a rapid assessment must be made as to whether he is dead or wounded, and whether the situation allows for you to safely pull him to cover. A dead teammate can wait, whereas a wounded one may need immediate attention from a medic and your action may be the deciding factor between life and death. If your buddy goes down, call out to the other fireteam buddy team and get them to cover you while you drag him to safety. Once you've made it to cover, call out to the squad medic and ensure that your buddy is treated. Depending on the tactical situation, you may want to stay to provide security for the medic, or move back to the fireteam and continue fighting.
