The US Air Force has posted a website link to Basic Military Class Photos going back to 1940s. Most are showing Lackland AFB Training Center, but others are before that. So if you served and had a Basic Class photo taken you may find yours and download free and keep for your family & Friends. Sadly, not all can be found as I learned for myself.
So find the year you enter into basic training and Month jump ahead about a month and BINO there is your old Class of Friends. More helpful if you can recall you Flight number. Here is the LINK and feel free to share with anyone: https://www.bmtflightphotos.af.mil/1960s/
