Soldiers, rangers, die on manoeuvres (10)

I believe the answer is:

grenadiers

'soldiers' is the definition.
(grenadier is a kind of soldier)

'rangers die on manoeuvres' is the wordplay.
'on' means one lot of letters go next to another.
'manoeuvres' indicates anagramming the letters.
'rangers' after 'die' is 'dierangers'.
'dierangers' anagrammed gives 'GRENADIERS'.

I've seen this clue in The Telegraph.
