Soldiers ordered to carry kit (7)
I believe the answer is:
brigade
'soldiers' is the definition.
(I've seen this before)
'ordered to carry kit' is the wordplay.
'ordered' becomes 'bade' (past tense of 'bid' as in to order).
'to carry' is an insertion indicator.
'kit' becomes 'rig' (I've seen this before).
'bade' placed around 'rig' is 'BRIGADE'.
(Other definitions for brigade that I've seen before include "Body of troops" , "Army unit" , "Rig a bed (anag)" , "Set of troops" , "Army grouping" .)
