Can soldiers in civilian clothes salute a fallen comrade memorial?

The answer is at the 2:30 mark of the video. https://www.youtube.com/watch?v=-MYxtpGxGJI

Anyone telling someone they can’t salute needs to find better things to do with their time, seriously.
It’s a sign of respect, no mater who you are.

YES

Absolutely can, I do it every time I walk past the deceased veterans memorial hanging on the wall at in my walmart store

Yes they can.

Yes. Screw 'the law' or whatever tradition. This is America. We have a constitutional right to express ourselves and one should NEVER feel guilty about showing honor and respect to another person, in whatever way feels appropriate at the time. What are you going to do? Go home and change your clothes? No. If you feel saluting is the most honorable way to express your respect, then do it. If you feel it is saying hello and shaking his hand. Do that too.
Don't ever get hung up on protocol when it comes to being kind. Even if you are in uniform, always do the right thing over the 'traditional'. Sure, there's a time and place to 'play the game' and follow all the customs and rules, obviously, but in real life, you need to use your mind and heart and adjust to circumstances.

I’m a veteran and no dam defense authorization act is gonna tell me what I can do. Next your gonna try and strip me of my discharge. Country’s went to hell along with how the military’s run. Good luck with your reforming of the country and volunteer force which is disappearing for good reason. No offense to brothers in arms.

REGS OR NOT I GOT A BIG MIDDLE FINGER FOR THE CODE OF CONDUCT. IF I WANT TO SALUTE IN A CLOWN SUIT OR CHIANS AND WHIPS IT'S NONE OF YOUR DAMN BUSINESS HOW OR IN WHAT I SALUTE A FALLEN COMRADE IN.
IT IS A GESTURE OF PURE RESPECT. NOT TRYING TO SOLVE THE WORLDS HUNGER.

WALK UP RENDER YOUR SALUTE, ABOUT FACE AND KEEP IT MOVING.......

SOMEONE HAS A PROBLEM JUST KEEP WALKING....

Yes

Frankly I can’t believe it took over two centuries to be codified as ‘approved’.
