.You're doing this thing where you're implying that's A: All REs are good for, and B: Somehow this investment the USF are making is absurd compared to the 200mp (And potentially 30muni) investment that Ostheer arguably always must make?
USF is designed around crew repairs. Requiring a 2nd RE being built means you spend mp building it that could go on another unit, just so the Pershing can function normally. 2 REs is not the same as 2 Pios.
