You typically say “Happy Veterans Day” to veterans and military personnel who you know, and you can accompany it with a more personal expression of appreciation such as “Thank you for your service” or “I’m grateful for your sacrifice.” The most appropriate approach can depend on your relationship with the person and their preferences. Key guidance

• To veterans you know personally: A genuine, direct thank you along with a brief note about how their service has mattered to you is often best. You can add something specific if you know it (e.g., appreciation for a particular role or sacrifice).
• For strangers or public contexts: A simple, respectful sentiment such as “Happy Veterans Day” or “Thank you for your service” is generally appropriate, sometimes paired with a sincere greeting or a handshake if culturally appropriate.
• If you know their branch or background: A tailored message can feel more meaningful (e.g., acknowledging Army, Navy, Air Force, Marines, Coast Guard, or Space Force) without overdoing it.

Examples you can adapt

• “Happy Veterans Day, and thank you for your service.”
• “I appreciate everything you’ve done for our country—thank you.”
• “Happy Veterans Day. I’m grateful for your sacrifice and dedication.”

Cultural and personal notes

• Some veterans may prefer a more personal, less generic message. If possible, try to add a brief, specific expression of gratitude.
• If the veteran is dealing with difficult memories, a more subdued acknowledgment and a listening ear can be more appropriate than a broad tribute.

If you want, share a bit about the person (their branch, how you know them, and any preferences they’ve expressed), and craft a tailored message together.
