I saw this several places today, including https://www.hitc.com/en-gb/2021/05/15/armed-forces-day-2021/. Here’s the Wikipedia link: https://en.wikipedia.org/wiki/Armed_Forces_Day, specifically U. S. Armed Forces Day https://en.wikipedia.org/wiki/Armed_Forces_Day#United_States. YouTube video: https://www.youtube.com/watch?v=0O4BrnYvidU (about 1:32 minutes long). National Today: https://nationaltoday.com/armed-forces-day/.
Armed Forces Day is a national day in the USA dedicated to the people who work in the military across all six branches including the Air Force, Army, Coast Guard, Marine Corps, Navy, and the Space Force.
I have several family members who have served in various military departments and I remember their service today. I also remember friends and others who have served in the military throughout the history of this country. Let us not forget those who have served, are serving, or will serve in the future. First celebrated in May 1950.
