Systems Alliance Military Manual
The Systems Alliance MIlitary has two branches of service: the Systems Alliance Navy (SAN) and the Systems Alliance Marines (SAM). Both were created in the aftermath of the Colony Rebellion over a ten year transition period. The Ceres Homeguard and the Colony forces created the structure they would follow and the people of Earth eventually began to fill out the bulk of the forces. The SAN and SAM forces would inherit all UEG and Colony vehicles, ships, weapons, and armor. They would eventually go on to prune less desirable gear at least for the SAM, however the SAN still relies on a lot of old ships.
