Thanks a lot! :)

Yes, you're right!

Thank you. I think to say ''Happy Veterans Day'' is alright probably.

Basically, Veteran's Day is to honor those who have served our country by participating in past wars and battles, whether they be elders or young men and women. The most common phrase that someone would say to a veteran on this day is, " Thank you for your service." You can add on whatever you would like, as well, such as, "Thank you for honoring your country with your bravery in willingly serving your nation..." You can make it as simple or complex as you want, but it's mainly thanking them for what they've done.

Thank you for your clarification. So I just wanted to make sure, Is it correct to say "Thank you for your service." if I am not living in the US and I am Russian?
