May 11, Ordnance and Tactical Systems Recovery from Disabled Vehicle l Lightweight capability enables the gunner to remove the weapons system from the destroyed vehicle, thus maintaining the combat power of the convoy

May 11, Ordnance and Tactical Systems Dismounted Overwatch l The dismounted ACSW provides additional security via a wider and better field of view than vehicle mounted l Employment in the 2 nd floor is less time consuming and requires less physical effort than dismounting the MK19 or M2 l Movement from primary to secondary positions is significantly quicker than with the M2 or MK19 because of the weight l ACSW tripod does not require sandbags because of low recoil

May 11, Ordnance and Tactical Systems Action on the Landing Zone l Reduced weight enables the gunner to mount the ACSW by himself and in less time, allowing more soldiers to perform security l This reduces the time available to the enemy to prepare for a counterattack, thus increasing combat effectiveness Scene 1Scene 2Scene 3

May 11, Ordnance and Tactical Systems Fast Roping the ACSW l The lightweight ACSW permits the establishment of a blocking position with a heavy caliber or grenade machinegun l The capability to fast rope allows a dramatic increase in dismounted blocking position firepower l Low system weight allows team to move weapon on ground as needed

May 11, Ordnance and Tactical Systems ACSW Summary l Provides New Weapon Capabilities l Passed All ATD Exit Criteria l Poised for the SDD Phase l Driving towards Low Rate Initial Production ACSW: Combat Weapon of the Future
