OT _ Artillery Query

[Littlearmies]

Hi,
One of my wife's friends has just deployed to Afghanistan and sent her an eBluey to say hello. His return address is given as CPIF Battery, 5 RA.

While I obviously appreciate who the 5th Royal Artillery are, what is a CPIF battery?

Thanks
Malc

Obviously this also means I have a new address to send my old books to - my company manged a respectable 23 parcels to the Marines last time round (not bad for 32 staff).
