"Smitty" Smith was a male Human security guard in the United States Military Forces in the 1960s. In 1968, he was assigned to Project Hercules, guarding the test site for the project's enhanced fusion bomb. Just prior to the bomb's test detonation, Smitty overheard Dr. Diana Winters reveal to Gary Seven that she was a KGB agent planning to steal American technology. In response, Smitty shot and killed Winters. (TOS - Star Trek: Assignment: Earth comic: "Brighter Than a Thousand Suns")
