'soldier' becomes 'NCO' (non-commissioned officer).
'in' is an insertion indicator.
'outskirts of epsom' becomes 'em' (I can't explain this - if you can you should give a lot more credence to this answer).
'overtaken' becomes 'passed' ('pass' can be a synonym of 'overtake').
'nco' going inside 'em' is 'encom'.
'encom'+'passed'='ENCOMPASSED'

'and' is the link.
