During my days in the National Guard flying Hueys and Kiowas.....30th Infantry Division Policy was no Rings allowed...and was strictly enforced due to far too many lost fingers
Old Chum of mine was missing one of his fingers due to his wedding ring getting trapped inside an aircraft step (the kind with the spring operated push in door) when he slipped and fell.
Leave those Rings at home.....plus for you geographical bacherlors or bachelorettes. over time that finger will gain an all over sun tan and ease your risk of getting rumbled while in pursuit.
