Agreed, and as much as people didn't like the Forward Supply Station it made more sense for a reserve force type commander to have a sort of makeshift HQ on the field rather than a static bunker that needs to be built solely by Pioneers and having weak reconnaissance abilities.
My opinion is that it should become the 223 upgrade for the 221 granting it the radio relay and forward retreat point similar to the OKW or replace it with the Forward Supply Station again but implement it properly this time.
Whatever,any ability better than this stupid bunker
