Disclaimer: I did not take part in any of the building, just found the base's performance impressive.

Usually, when Callahan's Gate falls, it only takes days for collies to secure Crumbling Post and then slowly creep north.

This war, they never made it past Crumbling Passage. Here is the bunker base that stopped them for several weeks until war's end, made by AESIR and 3rd in particular.

You can see the east fort recovering from a 300mm shelling, the center with the IC for the nuke aimed at Pits still alive and the NW under severe decay in the last hours of the war. You can also spot a collie bomber who tried to come back from a nuke attempt, and a torp bomber who never landed after fighting the DDs.
