Dayglo Army Lynxs

Hello
I was at Brize on Friday when a flight of three Army Lynxs with dayglo doors and upper tail booms came through. I have never seen this before and the only photo i could find http://www.airliners.net/open.file/1180441/L/ was 15 years old. I have not seen any references to these. Are they used for training? Based where? (Middle Wallop?) How many are there, and what serials? I assume they are not deployed.
Many thanks in advance.
