Dropping unit from sky appears to get rotor damaged (12)

I believe the answer is:

paratroopers

'dropping unit from sky' is the definition.
(unit of soldiers who drop from the sky)

'appears to get rotor damaged' is the wordplay.
'to get' means one lot of letters go next to another.
'damaged' is an anagram indicator.
'appears'+'rotor'='appearsrotor'
'appearsrotor' anagrammed gives 'PARATROOPERS'.

I've seen this clue in The Guardian.
