ICBM in a modified personnel carrier (7)

I believe the answer is:

minicab

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

'personnel carrier' is the definition.
Both the answer and definition are singular nouns.
Perhaps there's a link between them I don't understand?

'icbm in a modified' is the wordplay.
'modified' indicates an anagram.
'icbm'+'in'+'a'='icbmina'
'icbmina' with letters rearranged gives 'MINICAB'.

Can you help me to learn more?

(Other definitions for minicab that I've seen before include "Type of car hire" , "Car used as taxi" , "transport" , "It can't be hailed in the street" , "Type of taxi" .)

I've seen this clue in The Sun.
