Eikoh Goya ©Stars and StripesOkinawa, January, 1968: During the 30th Artillery Brigade's annual firing practice, Staff Sgt. Donald Ziegelbaver, left, plots a Nike-Hercules missile's course toward an ''unidentified object" as Lt. Wayne Tokiwa, Spec. 5 Allan Imhoff and Staff Sgt. Robert Blount man the controls. Standing at center is the chief evaluator, Maj. Herbert Siegel. The 39-foot-long (including booster) Nike-Hercules was directed to its target through ground-based guidance, unlike the other stalwart of the Army arsenal, the Hawk, which featured an internal guidance system.
