during the 2000s, the size of the directorate increased substantially with the inclusion of the special forces support group, joint special forces aviation wing and the special reconnaissance regiment (formerly 14th intelligence company). this was to meet a demand for a special reconnaissance capability identified in the "strategic defence review: a new chapter" published in 2002 in response to the 2001 september 11 attacks.. however there was a reduction in the scope of uk special forces when, following a review, it was found that the sas reserve lacked a clearly defined role, and also stated that the reservists lacked the capability, equipment, and skills to serve alongside the regular special forces. as an outcome of this review, on 1 september 2014, 21 and 23 sas were removed from the uksf order of battle and placed with the hac under the command of 1st intelligence, surveillance and reconnaissance brigade.
