How can I pass (( retake red square)) in call of duty .

There are several versions of Call of Duty. Which one do you have? At any rate you need to go online and get a walk through, print it out and follow the directions. Pretty easy to solve if you know how to do it.

In number one you have to like run full sped (unarmed) with the rest of the crew until you reach a seargeant. You then fight with him up to the top of a building where you use a sniper rife to shoot the enemy officers

Yep
