A lot like the Shade Turret, I think that that rear gun of the warthog variants should be forgeable as a stationary turret like the ones featured in Halo 3: ODST campaign. This would eliminate the need to forge a whole warthog and then surrounding it in other objects so only the turret can be used. I think we all can agree this was an issue in forge 2.0. They could give us the standard anti-air gun, gauss, rocket, and maybe any new type of warthog's gun in Halo 4. Any thoughts?
