Al,
See here for the
Annual Rates of Service Retired Pay for 2* and above.
I expect you're looking at how the new lower limits to the annual allowance for pensions is going to impact the high and mighty. Considering that the average 2* will be using about half of his £50k annual pension allowance every year whilst in that rank, he won't have much unused allowance to roll over from the previous 3 years to help when he gets promoted to 3*. I therefore suspect it will hit them quite hard!
