GAF follows the same general rule with regard to the uniform competion. If you win in a GAF competiion, the uniform can't be worn in another GAF competion (which so far is only the GAF Muster, but I see this expanding before long).
However, winning in a SASS or NCOWS competion, does not prohibit wearing the same uniform in a GAF competion. Nor does winning in a GAF Competion prohibit it from being worn in a SASS or NCOWS competion.
Too bad SASS and NCOWS don't have a rule that once a set of guns have been used to win a competion, they can't be used to win again!
All that said, Well Done to Bvt Lt Col and Maj Matt Lewis for his excellent accomplishment.
This achievement entitles Maj Lewis to a Star of Merit. However, until the website can be brought back up to date, you'll just have to hold on to that information until then.
