Mock battle with soldiers invading abandoned TA centre (2-9)

I believe the answer is:

re-enactment

'mock battle' is the definition.

'soldiers invading abandoned ta centre' is the wordplay.
I cannot quite understand how this works, but
'soldiers' could be 'men' (I've seen this before) and 'men' is found within the answer.
This explanation may well be incorrect...

'with' acts as a link.

I've seen this clue in The Independent.
