Ordnance and Tactical Systems 17 Action on the Landing Zone Reduced weight enables the gunner to mount the ACSW by himself and in less time, allowing more soldiers to perform security This Scene reduces the time available to the enemy to prepare for a 1 Scene 2 Scene 3 counterattack, thus increasing combat effectiveness May 11, 2004 Ordnance and Tactical Systems 18 Fast Roping the ACSW The lightweight ACSW permits the establishment of a blocking position with a heavy caliber or grenade machinegun The capability to fast rope allows a dramatic increase in dismounted blocking position firepower Low system weight allows team to move weapon on ground as needed
