Mobile Suit Gundam: Battle Operation (PS3): RGM-79(G) GM Ground Type WR Gameplay

I think the WR stands for "Weapons Rack," referring to the big container backpack. Don't quote me, though. (Also, technically I don't think GM Grounds should be able to carry those containers since they don't have the unfolding backpacks the Gundam Grounds use to carry those. But oh well.) I also don't do half as well with this as I do the Guncannon MPT.
