Can soldiers in civilian clothes salute a fallen comrade memorial?

You're God da*^ed right he can. The expression of respect can't be frowned upon.

why wouldn't you wanna walk over and stand wit ha brother in arms, render the same honor and respect he's showing... that would've been a moment BOTH of you live with forever into eternity...

I retired from the US Army June ‘90 and have always rendered a hand salute on every occasion that I would have while on active duty. I do still.

Why is this a question?

I saw a couple of comments here that are pretty funny and stupid. I do have a question though... exactly what "regulation" prohibits one from saluting a deceased soldier at the burial site while in civilian clothing?

Yes, and we should. There are fewer of us per capita in the country, and especially in Congress. We do well to honor those among us, as well as those who have passed, who served our nation at any point, especially in times of need and threat.

I truly try to be honest when I join a comment on this wonderful community of soldiers of all kinds and I love saluting when I go to baseball games or football games and the national anthem is playing I come to attention and I give a crisp clean snap salute until it is done I really really don't understand why people have such a hard time with things are right I wonder why they would rather find a way to fight things the best part of saluting is no matter what rank you are they have to salute back and I see it as the officers respect me also as a soldier that made it so sue me

Yes

Yes,
