so yea you control above the tunnel therefore they cant spawn , so you build a hab sw/west border above the tunnel yours wont be proxied but is close enough for your team to have complete control above , its just a matter of slowly grinding them down eventually you will get in enough GL's/Frags rounds and just killing them with some aggression of players to make a push through they will run low on ammo eventually with all the stupid 50 cals wasting it up so there medics will be low on bandages there AT's will have to rockets therefore your vics will start locking down entrances ... a big thing for this would be have your AT's camping the forward roads so they cant resupply ammo ... for the record good players will laugh at superfobs because we know how worthless they are , that guy on the 50 cal will waste shit tone of ammo and kill nothing while a rifelman will just shoot him in the head waste of time all that shit better to push out and secure ground
