Officer commanding sect in supernatural forces (6)
I believe the answer is:
occult
'supernatural forces' is the definition.
(I've seen this before)
'officer commanding sect' is the wordplay.
'officer commanding' becomes 'oc' (this could be a standard abbreviation I've not previously seen).
'sect' becomes 'cult' (I've seen this in other clues).
'oc'+'cult'='OCCULT'
'in' acts as a link.
Can you help me to learn more?
(Other definitions for occult that I've seen before include "Supernatural forces and events and beings" , "Supernatural practices" , "Magical; secret" , "Mystical (black arts)" , "Esoteric, magical" .)
