armoured car

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

'military vehicle' is the definition.
(I've seen this before)

'a royal marine alongside remote university racecourse' is the wordplay.
'royal marine' becomes 'RM' (abbreviation).
'alongside' is a charade indicator (letters next to each other).
'remote university' becomes 'ou' (I am not sure about the 'remote' bit.).
'racecourse' becomes 'redcar' (racecourse in North Yorkshire).
'a'+'rm'+'ou'+'redcar'='ARMOURED CAR'

'and' acts as a link.

Can you help me to learn more?

(Other definitions for armoured car that I've seen before include "Military vehicle" , "Reinforced vehicle" , "Heavily-protected vehicle" .)
