How do you respond when someone says "Thank you for your service"?

I simply respond "You were worth the sacrifice".

“Thank you for your support” is more than appropriate.
If a teacher, police officer, first responder, or someone in a service, I respond with “thank you for your service.”

I'm a Vietnam combat Veteran and I wasn't thanked then when I came home and don't want to be thanked now, it's meaningless to me! But my response is always the same. 'It was an honor to serve!' No, I don't add a thank you.

At first, it was an awkward moment where someone approaching me just to be nice was unexpected and found myself struggling for the right words, barely getting out nothing more than "you're welcome". As time passed, I recognized that some people just wanted to express their gratitude while others used it as an icebreaker to engage in conversation. My reply now is "you're welcome, and I appreciate your support". If they linger a moment then that's a chance to start up a conversation. People have questions and who better than vets to answer them! Granted, as more time passes since our service some things will change and certain insights become obsolete. At the end of the day, you get an opportunity to change or shape perceptions about military service.

I served near the end of the Vietnam war. I did not go to Vietnam, but every senior NCO and officer Captain and above had. These are the men who prepared me for combat as well as was possible without experiencing it. When Saigon fell I saw more than one tear on the faces of men who bore the physical and emotional scars of that war and who were often derided in public when in uniform, as was I even though I had never fired a shot in anger. When I first got out I kept a low profile on my veteran status, but the public perception of the military changed after the first gulf war, and I began to hear “Thank you for your service.” At first, I was bothered by this because I did not think I had done anything worthy of praise in comparison to what the Vietnam Vets had gone through. I eventually accepted it and now proudly wear my “Thank me for my service” hat, and when thanked I reply with a sincere “I appreciate that” and hope that these men lived long enough to receive this praise they truly deserved.

Thank you for your support

I always respond the same way. I thank them for allowing me to serve the greatest nation and the greatest people in the history of the world. Because in my mind it is a joint effort between tax payers and service men and women that makes it happen.

I'd do it all again; met my She there and she put up with me for 43 years.

Thank you for your support. OR, Thanks

I tell them thank you and that the country an them were worth it.
