Scuttled,
Agreed. Ignore the jealousy of certain bell ends who can't be bothered to find out the facts. You should not be financially disadvantaged, full stop. ISTR another poster mentioning similar. I also know of people who have turned down the opportunity because of this.
Keeping the missus happy is one of the tricky things when serving in HM Forces. It's why so many marriages go down the pan. I for one will not be volunteering for a overseas post as I'm unwilling to be seen off financially by the very people who want me to go abroad. Madness.
Thanks for the warning.
