One big gotcha was that the extra money now paid so that it could be deducted for food and accommodation was pensionable
And there lies one of the bigger faults in the current services compensation package. The inflexibility of the pension scheme is an impediment to labour mobility in the military. It is an obstacle to personnel taking sabbaticals from the military then rejoining after a few years. It is also an obstacle to late-entry into the military. It is also the cause of those maligned low-paid jobs targeted at recently retired servicemen.
