I read somewhere that if a serviceman is married in uniform, and say is a corporal, then he is allowed to wear sergeant stripes for the day, i.e all service personell are allowed to be 'promoted for the day' on their wedding day.
I can not find any corroboration of this ??
I can't say I've ever heard of this. Been to a few military weddings (including one I partook in, in error), and none of the servicemen had "extra" stripes for the day.
I haven't heard of this. I have known other ranks use ceremonial swords for the wedding ceremony which is bending the rules - swords usually only for commissioned officers.
