I believe it was in 1974 – SSG Fred "Scooby" Stevens and his partner SGT Bryan Buchannan, both of the 401st MP Company, responded to a domestic complaint. There was a NCO with a shotgun shooting up his house and threatening to kill his wife.
When the patrol arrived they approached the front door and the wife came running out. The NCO was armed with a 12 guage shotgun and he pointed it at his wife.
Scooby told him to "Drop the #!%! Shotgun!"
