Sgt. Sapuro Nena, Spec. Genaro Bedoy and Pfc. Jon Townsend were honored at Joint Base Lewis-McChord on Wednesday.
Up to one month ago, U.S.soldiers worked side by side with Afghan troops and police, helping to train them. But the deaths of the three Stryker soldiers changed that.
The families of the fallen soldiers were overcome with grief at their memorial service. All three men had been married, and Bedoy was a father.
The focus of the ceremony was how the men had lived, not how they died.
The trio was gunned down by an Afghan officer who killed one more U.S. troop before killing himself. From that point on, NATO troops pulled back from teaming up with Afghan troops, unsure who the enemy is.
While their fellow 3rd Stryker brigade soldiers carried on the mission, their troops at home honored their memories.
"Rest in peace, brother," said Sgt. Jesse Ayin. "Your soul will never be forgotten."
