Navy's football rival (4)

Ross

I believe the answer is:

army

'navy's football rival' is the definition.
(I've seen this in another clue)

This is the entire clue.

(Other definitions for army that I've seen before include "Fighting force" , "See 21" , "A great number (of soldiers?)" , "Body of people organised for war" , "Large number (of ants?)" .)

I've seen this clue in the USA Today, The New York Times and the Universal.
