Clayton Callahan has made his living principally in the "uniforms and guns" professions. Just out of high school in the 1980s he first served in the US Navy with an anti-terrorist unit. After 9/11 he enlisted in the US Army and is now an Iraq War veteran twice over. Between active-duty deployments, he's worked as a deputy sheriff, a correctional officer, and as a federal special agent for US Army Counterintelligence (lots of great stories there, can't tell any of them).
His focus is on science fiction, but also has been known to dabble in spy thrillers, game desigen, and non-fiction works. Check out his blog at claytonjcallahan.wordpress.com
