[Girls' Frontline] Chapter 11-2 Emergency S Rank Guide (2 Combat Echelons)
No RNG here, and I'm not even sure there are that many solve variations, given the places you need the tanks to move to are set in stone, and enemies never move aside from the tanks. Probably don't need to actually cap the lower left helipad, but I did in case I messed up some movement for more leniency. You can use rifles on the gundam if it is too hard or you lack M4 Mod 3.
