Military advisors run off after ideas misfiring (5-2-4)

'military advisors' is the definition.
The definition and answer can be both people as well as being plural nouns.
Perhaps there's an association between them I don't understand?

'run off after ideas misfiring' is the wordplay.
I cannot quite understand how this works, but
an anagram of 'ideas' is 'aides' which is located in the answer.
'run off' could be 'decamp' (synonyms) and 'decamp' is found within the answer.
This accounts for all the letters.
This may be the basis of the clue (or it may be nonsense).

Can you help me to learn more?
