Check out the CPWS video! Those are two Javelin ATGMs on the side and this turret has 40mm smoke grenade launchers, something other RWS turrets do not have, not to mention the ability to reload under armor. And that was a problem in Afghanistan FOBs in which many HMMWV gunners were hit in the open turret and many HMMWV crews cowered inside because no one wanted to get out and reload the turret .50cal because it was exposed.
