Thank you both for the response. As a Marine I can’t salute without a cover, it isn’t natural. Which has caused some interesting moments in life with inter-service responsibilities.
I can understand that.. as a Air Force Vet.. I find it unnatural to this day to walk into a building with a hat (cover) on.. or walk out of one without one.
But I have learned over time to overcome those ingrained urges... its still there.. but suppressed.
