Grenadier-carried, prone-fired automatic grenade launcher. Similar in function to the DUMG or HEMG. Works as an alternative to the RPG (select between them two). Inspiration: http://en.wikipedia.org/wiki/Mk_19_grenade_launcher
You understand that RPG and mortar is the same weapon, right? Also, terrible idea, we don't need more proning people in empires. At least not with 40 mm automatic grenade launchers.

I think you get my point now. An alternative anti-tank weapon, that can be turned against infantry for the grenadier. I wonder if the auto-GL could be tried out with some weapon scripting. Base it off the rifleman HMG, add damage to vehicles, nerf it against infantry.
