UNSC Naval Special Warfare Group Six (NAVSPECWAR Six) is a covert action detachment of UNSC Naval Special Warfare, UNSC Special Operations Command and UNSC Progressive Warfare Division (PROGWARDIV). Its primary responsibilities include covert action and unconventional warfare, and NAVSPECWAR Six has gained significant dubious distinction in military circles as a "black ops" group, and retired members have published extensive human rights abuses and humanitarian atrocities and usage of weapons of mass destruction perpetrated by NAVSPECWAR Six teams.
