Chappie, Nige et al.
Safeware is quite right and remember to up-rate those 2000 figures in line with inflation since 2000 (2-2.5% p.a.). Also, you could have a look at the supplimentary budget documents which may show the amount spent on UORs.
AFAIK, UORs are paid for from the additional funding for ops - the so-called Net Additional Cost of Military Operations (NACMO). This is new money, over and above the defence budget. (See John Reid on 14 Dec 05:

As "Deep Throat" said - follow the money!
