On April 25, 1951, Sgt. Edward G. Bunn heard Cpl. Charles L. Gilliland's automatic rifle firing in the darkness near Tongmang-ni, Korea. Gilliland always kept his weapon clean and fine-tuned. Bunn knew when his comrade was the one firing. In a chaotic firefight against waves of Chinese troops, the 17-year-old from Yellville, Arkansas, was using his weapon to hold the line. "If it weren't for this young man, Charles Gilliland, I wouldn't be standing here today," Bunn said decades later.
