Chapman Sweatshirt

As a old Army Infantry GRUNT, I would not have imagined I'd wear an airforce sweatshirt, but after reading Alone at dawn I feel honored to bring attention to this man and Dan Schillings book Alone at Dawn.

Honoring a legend

As an Air Force MSgt, it makes me proud to support this legend for our Air Force pride. I read Alone at Dawn, it made me proud of our CCT boys. He’s our John Basilone of the war on terror for the Air Force. Fly-Fight-Win.
