Nutloose,
NATO is no get out of AFG or any OOA. Whilst in NATO you may get a pass noting that many NATO postings involve a det to AFG. In truth you are likely to have just deployed or be top of the list after your tour. I deployed to Iraq during my NATO tour.
In recent years NATO tours have been easy to get and bad for promotion. Manning told the promotion element to an audience of 150 officers 3 years ago, of which I was one. Today there is a very strong push to reverse that.
