The comment that it is up to the senior military person on board that decides if uniform can be worn in the airport is wrong!!!
At Birm and even Man if a jet is diverted and on a quick turn then the passengers in civvies or uniform are not even usually allowed off the jet
The decision by Birm to not allow uniformed passengers to transit the terminal is an aiport decision!!! NOTHING to do with crew, passengers, snior officer!!! If the senior officer was to demand that passengers transit in unform it would be interesting to see how!!! airport would just refuse to provide transort or access
