okay, your at an indoor field with many rooms. how do you clear one out? talk with your team members and make a 4 man team. then when you approach the door, line up 2 people against each side of the wall. if the room has a door, wait for the teams okay before opening. if not, wait for the okay then rush in guns ready. for a diversion, throw a smoke grenade in, then rush in. think of the room as a square. there are 4 corners. each man rushes to his corner shooting. you must have full attention of your team while planning this assault. when you go in go as fast as you can to your corner and stay put while shooting at the enemy inside. when everyone is dead yell-clear! your team should reply-clear! then move on to the next room. if the room has a balcony, the men going to the far corners should run up the balcony shooting, and take those corners. agin yell-clear! when you are done. if possible to take a room by 2 entries take it. your team splits up into 2 man groups and 1 team by each door. then 1 team goes in first then the other. the 2nd team should listen for sound then rush in. remember when you do this you must be as fast as possible. dodge bb's to get to your corner. that corner is your safe haven if everything goes according to plan. if not, you might be able to take the enemy on your own, but its a very risky move. 10-90 odds you will live without ant of your team's support.
