Ordered to include equipment for military body (7)
I believe the answer is:
brigade
'military body' is the definition.
'brigade' can be an answer for 'body' (I have seen 'Body of troops' mean 'brigade' so perhaps 'body' could also mean 'brigade'). I'm unsure of the 'military' bit.
'ordered to include equipment' is the wordplay.
'ordered' becomes 'bade' (past tense of 'bid' as in to order).
'to include' is an insertion indicator.
'equipment' becomes 'rig' (rig is a kind of equipment).
'bade' enclosing 'rig' is 'BRIGADE'.
'for' acts as a link.
Can you help me to learn more?
(Other definitions for brigade that I've seen before include "Abridge (anag)" , "Set of troops" , "Army subdivision" , "Rig a bed (anag)" , "Body of troops" .)
