Part of U.S. Military Forces in FY 2021. Beyond the traditional military services, military forces include the new Space Force as well as Special Operations Forces (SOF, which functions as a quasi-service), Department of Defense (DOD) civilians (which perform many functions that military personnel perform in other countries), and contractors (which form a permanent element of the national security establishment, not only in the United States proper but also on overseas battlefields).
