Tackle promotion while sitting in funeral stand for officer (9)
I believe the answer is:
brigadier
'for officer' is the definition.
(brigadier is a kind of officer)
'tackle promotion while sitting in' is the wordplay.
'tackle' becomes 'rig' (I've seen this in other clues).
'promotion' becomes 'ad' (ad is a kind of promotion).
'while sitting' becomes 'bier' (I can't justify this - if you can you should give a lot more credence to this answer).
'in' indicates putting letters inside.
'rig'+'ad'='rigad'
'rigad' put inside 'bier' is 'BRIGADIER'.
'funeral stand' acts as a link.
This may not be right. Some or all of it may belong to another bit of the clue.
Can you help me to learn more?
(Other definitions for brigadier that I've seen before include "Air bridge over to the military officer" , "Army rank" , "Rank above colonel" , "High-ranking army officer" , "Military leader" .)
