One of the first things sailors are taught is flag etiquette. The rules are different for sailors, and many of the basic points of etiquette are not understood by civilians.
Here are a few of the "flag rules" sailors learn. Please help your sailor follow them.
During the National Anthem, sailors must stand at attention and salute the flag. They do NOT put their hand on their heart, or remove their hat. If indoors, they stand at attention and may NOT put their hand on their heart. Sailors also may not recite the Pledge of Allegiance while in uniform, they are required to stand at attention, silently. I have heard/seen soldiers and sailors being yelled at for breaking the civilian traditions surrounding the flag. Please let them honor the flag while in uniform as they were taught.
Your sailor will be required to salute any flag they pass, beginning three steps before they reach the flag, and three steps after. That means ANY U.S. flag, including those in front of banks, private displays, any U.S. flag you may walk buy as you accompany them on liberty. Make sure you walk on their left and do not ask them to carry anything in their right hand, as they must be ready and able to salute a flag (or an officer) at a moment's notice.
Do NOT wear the flag in any form of clothing. That means a shirt styled to look like the flag, or featuring stars and stripes, as if made from a flag. Do not wear a sweater with an embroidered flag, and especially a shirt or sweatshirt with a flag print. All of those forms of wear are considered disrespectful as you drip food on them, wash them, wear them out and eventually throw them away. If you must wear a flag of some sort, wear a flag pin or broach.
And when you entertain, never, ever use flag-decorated tableware, including napkins, plates, etc. If it's not right to wear the flag on your clothes, just thing about the disrespect in putting food on the flag (on a plate) and wiping your face with the flag (on a napkin)!
Ladies, do not remove your hat during the National Anthem. Only men are to remove their hat. This is one of the most universally misunderstood points of flag etiquette. This rule goes back to the days when women pinned their hats into their hair and could not remove and replace a hat easily. The wearing of women's hats has changed, but the etiquette has not.
