Gender inequality!
Regulation MCO P1020.34F of the Marine Corps Uniform Regulations chapter 3, rules out any use or carrying of an umbrella while a Marine is in uniform.
However, female Marines 'may carry an all-black, plain standard or collapsible umbrella at their option during inclement weather with the service and dress uniforms. It will be carried in the left hand so that the hand salute can be properly rendered.
Couldn't happen here could it?
Edited to add - please carry on as usual ladies and gentlemen, I enjoy reading this forum.
By the way, what about "sauntering"?
