Fighter breaking a rule badly gets long reprimand (6)

I believe the answer is:

earful

I'm a little stuck... Click here to teach me more about this clue!

'long reprimand' is the definition.
'earful' can be an answer for 'reprimand' (I've seen this before). I'm not certain of the 'long' bit.

'fighter breaking a rule badly' is the wordplay.
'fighter' becomes 'F' (abbreviation in war plane e.g. F-16 etc.).
'breaking' indicates putting letters inside.
'badly' is an anagram indicator (letters in the wrong order).
'a'+'rule'='arule'
'arule' anagrammed gives 'earul'.
'f' put into 'earul' is 'EARFUL'.

'gets' is the link.

Can you help me to learn more?

(Other definitions for earful that I've seen before include "Prolonged reprimand (colloq.)" , "Rocket" , "Ale fur (anag.)" , "Severe reprimand" , "A telling-off" .)
