Sir,
The M6 Bradley ?Linebacker? had a crew of 4. This consisted of the driver, gunner, Bradley Commander and loader. M6 Linebackers often ran with only three man crews and in Iraq the 4-5 ADA ran often with only 2 man crews the commander pulling the duty of the gunner and commander. Also the stinger racks for Linebackers associated with the 1st Cavalry (4-5 ADA) removed their stinger racks in the back in favor of carrying more ammunition and also removed their FBCB2 or ?blue Force trackers? to allow easier access to the co-axle machine gun.
