Something I was considering letting the Radar Dome do to give it more presence was add a terminal that, if the WF is dead (but not if it doesn't exist i.e. Hostile/Seamist), can be used to buy a Medium/Heavy Tank for double the standard price once every so often (maybe a 2 minute timer), which would be airlifted in by a Chinook just like on Seamist. That's kind of like the reinforcement bay except not free - free vehicles kind of kill the point of the economy I'd say. But that only gives more presence for potential comebacks to one of the non-production buildings...
