Valky Better Space Marine Production

Description: All this mod does is add a second of each major production building as an Auxiliary (Infantry, Vehicle, Aircraft, and Building) to literally double the number of units the SM city can produce, making fielding large armies a little easier for SM without having to resort to giving them the ability to place down one or more extra cities.

Compatibility: Should be compatible with literally any mod out there, if anything will break it it'll be any mod that changes the construction building for SM.
