Military supporters like you have stepped up to sign the card and honor our heroes on the U.S. Air Force’s 76th birthday — but we were shocked to see you haven’t added your name!

We know you wouldn’t want our brave service members to feel forgotten on this important day, so we’re reaching out one last time before the midnight deadline to ask: Please, will you sign the USAF birthday card to thank our heroes in uniform for all they do?

This is your FINAL reminder, so please, don’t delay:

Thanks for standing with our service members as they make incredible sacrifices to defend our country.
