Capt Gruters next served as an O-1 forward air controller with the 19th Tactical Air Support Squadron at Bien Hoa AB, South Vietnam, from March to September 1967, followed by service as an F-100 Misty Super FAC at Phu Cat AB, South Vietnam, from September 1967 until he was forced to eject over North Vietnam and was taken as a Prisoner of War on December 20, 1967.

His 2nd Silver Star Citation reads:
Captain Guy D. Gruters distinguished himself by gallantry in connection with military operations against an opposing armed force as a Forward Air Controller over North Vietnam on 23 October 1967. On that date, Captain Gruters directed fighter operations against a large concentration of hostile 57 millimeter antiaircraft artillery. With complete disregard for his own safety, Captain Gruters repeatedly flew his unarmed F-100 aircraft across the target to intentionally draw the groundfire, thus exposing the exact positions of the hostile guns and minimizing the danger for the other pilots. By his gallantry and devotion to duty, Captain Gruters has reflected great credit upon himself and the United States Air Force.
