Perhaps I'm off on the numbers - but they were drawn from a review of the info supplied
here:
Equally it is likely that units will be attached and detached so some formations will be below strength and others over strength. Perhaps some could even lose their Infantry and gain an Armoured group from another formation.
The groupings below are entirely notional, with the exception of 3 RM Cdo Bde and 16 Air Assault Brigade (currently serving in Afghanistan and heavily reinforced). The notional groupings do reflect the SDSR Structure and the latest reorg of the Infantry and Artillery.
NOTE - 1 Duke of Lancaster's is not currently an Armoured Infantry Battalion but there were 21 Light Bns and only 9 Armoured/Mech Bns so I took the liberty of moving the Dukes to the Armoured Infantry column as they were the only regiment that didn't have an Armoured Infantry Battalion.
Yes there is an element of speculation here but I don't believe the numbers are far off the mark.
Edit - And I wouldn't be surprised if each formation DID indeed lose 1 or even 2 "Feeder" Battalions of Lt Infantry.
