On Aug. 8, 2012, I lost a friend, four families lost their husband and fathers, and the country gained a hero. My friend Command Sgt. Maj. Kevin Griffin, Majs. Tom Kennedy and Maj. David Gray, and USAID Foreign Service Officer Ragaei Abdelfattah were killed when a suicide bomber walked up to them and detonated while they were traveling by foot en route to a key leader engagement in the town of Asadbad in Afghanistan. The resulting explosion was so large that it triggered the detonation of a second bomber who was waiting to exploit the resulting breach in the security perimeter. Their ultimate target was Col. James Mingus, commander of 4th Brigade 4th Infantry Division out of Fort Carson, Colorado, who was on his way.
