Heckler & Koch MP7ue 4.6x30mm (Union designation: 'SMG1')
The MP7 Union Edition is a modified model of the standard HK model MP7. It is small, compact, and feature a collapsible foregrip and stock, so the user can fire it like a machine pistol or a small carbine.
The MP7 is used by all branches of
Overwatch, including
Civil Protection on raids. Because of its bountiful ammunition supplies and ability to quickly bring CPs down, the SMG is a favorite of rebels.
The
Union Edition signifies one small addition; a 20mm airburst grenade launch attached under the main barrel. Ammunition is less common for this attachment, but is extremely effective at bringing down groups of clustered enemies.
