In the fictional BattleTech Universe, the Armed Forces of the Federated Suns (AFFS) was the military branch of the Federated Suns, the Successor State ruled for most of its history by House Davion. After 3054 it was integrated into the Armed Forces of the Federated Commonwealth (AFFC). This organization was short-lived, however, as the AFFC was largely folded back into the Federated Suns State Command after the Lyran secession in 3057. Ten years later, the AFFC was renamed the AFFS in conjunction with the renaming of the nation.
