Saturday brought yet another tragedy in Afghanistan. Another fatal attack on American troops in a 19-year war that continues with no light at the end of the tunnel.

The shooting in Afghanistan’s eastern Nangarhar province lasted mere minutes when an individual wearing an Afghan army uniform opened fire on a squad of U.S. special operations troops. The military is still investigating whether the assailant was actually a member of the Afghan security forces or a Taliban infiltrator, but the result is still the same: two slain American heroes by the names of Sgt. Javier Jaguar Gutierrez and Sgt. Antonio Rey Rodriguez, the latter serving his 10th deployment in 11 years.
