Getting out of phone contract

I remember the cases of British soldiers posted to Afghanistan who had still had to see out their contracts. It was on Watchdog and everything.

Devil's advocate: How would you feel about British government officials/ministers working overseas allowed to get out of their contracts? Or bankers posted to a foreign bank..

Mind you, Aussie soldiers get a lot of perks for risking their lives. It sounds to me like British soldiers get a fucking raw deal a lot of the time.
