Do you see the image inside the tweet?

It's of a veteran specifically thanking the Q team.

Dear Team Q, On such a special day, and on behalf of all veterans, we give you a salute of respect, admiration, gratitude and love for putting your lives on the line, so that the rest of us can finally become truly free. Thank you, and your family and friends that worry about you, and may God keep his hands of protection wrapped lovingly around you. With love, honor and respect, Anonymous American Vet
