There were alot more than 10 Harriers deployed on Telic, with the same number again as in Kuwait in Harrier Force South, deployed in another ME country as Harrier Force North.
That means the 2/3rds force required now is even larger than you suggest. However how much of that FJ support is now provided by Reaper, which we didn't have back then?
We are too small to do much more than an enduring small commitment with another SSFI op for surge periods though. And one day we are probably going to lose instead of win or withdraw.
Tough times.
