A pair of full-sized veterans of the First Cavalry Division's tour of duty during the 1990-91 Gulf War. AKA Desert Storm.
Why the Dress uniforms? A routine dress uniform inspection.
While the newer dress blue ASU worn by SSG Cooke looks sharper, I tend to prefer the older, green uniform as it's just a little more colorful with its unit patches and, if the soldier qualifies, combat patches.
