In addition to the new arsenal of HK weapons consisting of the MP-7 PDW, the MG-4 LMG, the 416 and 417 assault rifles, and a new US/German joint sniper rifle, there is the developing PPMD which originated with the old caseless HK G-11 and MG-300 weapons shelved in 1990 upon reunification. There was a caseless pistol design too that was dropped. With the IDZ Gladius program moving forward, the German Army and KSK want a new light ACR that is electronically integrated with their advanced EADs systems and comp network. But Rheinmetall AG is working on a Bundeswehr Plasma Rifle for use by 2020. With threats of terrorism and new tech, German advanced SEK units (equivalent or higher than US SWAT Teams) want a new pistol in their arsenal that can be used by the military too. The result is HK going back to the caseless pistol but with multi-barrels of various calibers, new electro-targeting, integrated dazzlers, and a locking taser weapon underneath. The military version would ditch the taser block for 4 tubes of 13-15mm guided rockets replaceing the standard 40mm GL. In this way the SEKs have a much more lethal weapon at their disposal while German HRUs and KSK can augment the MP-7 and their complex version of the G-36. The weapon is in development.

*EADS IDZ Phase II, which has been revised as the Gladius System. HK was NOT an original contributor to that phase but the dual-usage now qualifies them to submit a pistol design. IDZ currently use the HK MP-7 PDW due to availability- it was not made specifically for them but the entire Bundeswehr.
