The Joint HK/US Army XM-25 IAWS (Individual Airburst Weapon System) was pioneered by HK in the 2000s and handed over to the US Army for fine-tuning from 2009 forward. It is a 12.6 lb bullpup grenade launcher that features a 4-rd rear mag, TAFCS fire control system with day/night capability through optics and thermal-imaging, easy to reach laser rangefinder, and programmable smart rounds of 25mm. The operator activates the laser rangefinder, marks the target, and then can adjust the range of the munition for detonation. This information is imprinted on the round through a microchip and the smart GL analyzes the air pressure and counts the revolutions of the round to target for precision detonation above or inside a target area for 100% first kill probability. It has worked so far in combat ranges up to 500m and max area range of 1400m. It can also carry a flechette (arrow) round as well as thermobaric warhead for cave use. A welcomed weapon that the US Army wants to get their hands on for the ME wars, the XM-25 should become available in 2012. Already, the German weapon is known in the US as "The Punisher"!!!
