Gunner Henderson was a Marine Corps veteran and a member of the Cerberus Squad who served in Afghanistan alongside Frank Castle. Upon leaving the army, Henderson became fearful of being assassinated so hid out within the woods until Castle found him. Henderson and Castle were ambushed by William Rawlins' team and Henderson was eventually killed in the shootout.

Secluded in Fear
When it became apparent that he was being targeted, Henderson hid in the mountains of Kentucky. Though Frank Castle began searching for him and called out to him as a friend, Henderson fired an arrow from his bow and slowly approached. Convinced that Castle was not out to kill him, the two partnered up and, with the sounds of a coming helicopter and soldiers through the woods, fled to hide and kill off each one.
As the soldiers sent in by William Rawlins pursued Frank and Gunner, the pair was able to fend them off, however, Gunner was shot in the abdomen during the encounter. After the shootout, Gunner felt fatigued and was carried by Castle, who was also shot in the stomach. Gunner knowing that he would “die in these woods", requested Frank to bury him, but Frank left to search for help, leaving him alone while he died from blood loss.
