Alongside the SOF task forces operated the largely conventional CJTF-Mountain. Mountain initially comprised three subordinate commands, but only one was a special operations force - Task Force 64, a special forces task group built around a sabre squadron from the Australian SAS. The US Marines contributed Task Force 58, consisting of the 15th MEU, who were later replaced by Task Force Rakkasan. The JIATF-CT (better known as Task Force Bowie), led by Brigadier General Gary Harrell, was an intelligence integration and fusion activity manned by personnel from all Operation Enduring Freedom – Afghanistan (OEF-A) participating units, both US, coalition and a number of civilian intelligence and law enforcement agencies. Bowie numbered 36 military personnel and 57 from agencies such as FBI, NSA, and CIA, as well as liaison officers from coalition SOF. Administratively embedded within Bowie was Advanced Force Operations (AFO). AFO was a 45-man reconnaissance unit made up of Delta Force reconnaissance specialists augmented by selected SEALs from DEVGRU and supported by ISA's technical experts. AFO had been raised to support TF Sword and was tasked with intelligence preparation of the battlefield, working closely with the CIA and reported directly to TF Sword. AFO conducted covert reconnaissance - sending small 2 or 3 man teams into al-Qaeda 'Backyard' along the border with Pakistan, the AFO operators would deploy observation posts to watch and report enemy movements and numbers as well as environmental reconnaissance; much of the work was done on foot or ATVs. The final task force supporting OEF-A was CJCMOTF, which had the responsibility of managing civil affairs and humanitarian efforts.
