Sounds like you were fed a load of BS.
1) Officers don't train recruits. Sergeants (usually E6 and E7 grades) do as far as military training. An officer could teach a karate class in his personal time after duty hours but it would not be considered official government business.
2) Kenpo is not and was not the official hand-to-hand system taught to the US military; therefore...
3) They would not have trained during duty hours. They would train during their off-duty/free time--which means they would have had no mandatory uniform requirement.
4) Even if they had to train in the physical fitness uniform, there would be no reason they could not train, test, and advance in rank. They simply would not be able to wear the belt during class and would have had to simply keep it "at home". Even then, there's no reason they couldn't have been given a belt for their personal display or collection.
More nonsense...and you guys wonder why I shake my head at American Kenpo.
