a Strength figures are only approximate. Official 5th Special Forces Group reports contain numerous irreconcilable discrepancies, for instance, between the number of detachments with sector and subsector mission and total of Regional Forces and Popular Forces advised for September and December 1965.
b Included in totals of previous column. B detachments had sector mission and A detachments had subsector, but the subsector column includes some B detachments with both sector and subsector missions.
c Or equivalents.
d Not available.
