The Beginning (Pre-UNSC Period)
The United Nations Space Command began with the official establishment of the United Nations after World War II in 1945, creating for the first time in human history a political and military entity that could administrate worldwide economic, social and military matters such as operations and campaigns aimed at providing humanitarian aid and global military intervention with the objective of preserving peace in unstable regions. As space exploration progressed during the twenty-first century, colonization operations required international cooperation and assistance to effectively conduct territorial expansion throughout our Solar System. So soon later, the International Society of Civil Engineers was formed in 2021. The purpose of this organisation was to simply further the quality of space engineering, a memorial to their work had been built aboard the Quito Space Tether above Earth.

The worldwide changes encouraged governments to feel it was necessary to colonize in space. The only global administration organisation humanity could rely on to do this was the United Nations, who then took the initiative to lead. Doing so, the National Governments lost overall authority and their armies, could only be assumed, to have been absorbed by the United Nations military forces.

Organisation
As the main military branch of the UNSC, the UNSCDF is comprised of three autonomous or semi-autonomous branches, each with different functions and methods, but all unified under one command, and tasked with the protection of humanity, and the protection and recapture of human-occupied colonies. Control is exercised through regional CENTCOMs, which have authority over certain areas of space.

So far, the best-known members of the UNSCDF seem to be the Navy and Marine Corps, likely due to the space-oriented nature of 26th Century warfare. While also a part of the UNSCDF, the Army and Air Force are less well known.

Ranking System
Like all military forces, the UNSCDF military forces have their own ranking system.
