Combined Member National Subcommand

The Combined Member National Subcommand, or COMB-SUBCOM, is one of the three main parts of the Department of Security for the Coalition of Congressional Republics (the other two being the Coalition Forces Authority and the Security Intelligence Network). COMB-SUBCOM serves as the collective reserve force for the CFA due to the ability of transferring units between these two organizations, and also serves as the allied command between the individual armed forces of member Republics of the Coalition.
Due to the Coalition being allowed to have member Republics maintain their own armed forces as a part of the treaty that ended the Corporate Revolution of the 2200s, and having originally existed since the formation of the Coalition in 2077, the COMB-SUBCOM has accumulated a reputation as the "bulwark against corporate armies". However, corporate influence still has permeated the force, as seen with Elpian nations' armed forces within COMB-SUBCOM being primarily composed of converted corporate security outfits. They are also not allowed to deploy any forces on Earth due to Coalition legislation barring non-CFA deployments on the capital world; as a result, earthborne nations such as the United States and China deploy their forces in nation-owned infrastructure across the wider Coalition, or even deploy their troops in peacekeeping operations abroad.
The COMB-SUBCOM has currently multiple undergoing missions in complement and support to the Coalition Forces Authority, such as the Stellar Republic of Mera (a Coalition-supported stellar government of the Mera star system) reviving its national guard under COMB-SUBCOM administration to assist in the garrisoning of the recently re-taken world. The People's Republic of China has also volunteered to deploy units from the People's Liberation Army on Tupã Prime within the star system of Tupã as a means to phase out potentially vulnerable CFA units from attack by anti-Coalition insurgents.
