If the average loss per soldier, sailor and airman, is £1,400 then:
For every individual who loses CEA (for 1 child), an allowance that many on pprune have been quick to attack, with only a small minority defending, then about 9 others on average don't lose anything!
It would appear that for every senior officer and SNCO in the USA having their LOA reduced another 3 or 4 others on average lose nothing.
Indeed, rather than everyone losing £1,400 per year, there are some very big losers, and some (the majority) who lose a small amount of money...
I'm not saying that this is right or wrong, fair or unfair, just trying to point out that the £1,400 figure should be taken with a very large pinch of salt....
