capable of launching 9 pellets of depleted uranium rounds up to 1 km straight up into the air
Must be some sort of high performance round to go 1000 metres (~3300 feet) straight up. When I learned my tactical flying stuff in helos, the belief was that you were safe from small arms fire above 1500 feet AGL. New propellant? Longer barrels? Vivid imagination? 1 April?
