"Unconventional Warfare (UW) … remains uniquely Special Forces'. It is the soul of Special Forces: the willingness to accept its isolation and hardships defines the Special Forces soldier. Its training is both the keystone and standard of Special Forces Training: it has long been an article of faith, confirmed in over forty years of worldwide operations, that "If you can do the UW missions, you can do all others." The objective of UW and Special Forces' dedication to it is expressed in Special Forces' motto: De Oppresso Liber (to free the oppressed)."
