Kelly really regularly dispatched someone in the military (7)
I believe the answer is:
general
'someone in the military' is the definition.
The answer and definition can be both people as well as being singular nouns.
Perhaps you can see an association between them that I can't see?
'kelly really regularly dispatched' is the wordplay.
'kelly' becomes 'gene' (I've seen this in other clues).
'regularly dispatched' means one should take alternating letters (letters removed at regular intervals).
The alternate letters of 'really' are 'ral'.
'gene'+'ral'='GENERAL'
Can you help me to learn more?
(Other definitions for general that I've seen before include "Popular" , "Not partial, local or particular like army chief" , "Officer of the highest rank" , "Of wide application" , "The senior officer is common and widespread" .)
