Vietnam Tunnel Rats. Whenever troops would uncover a tunnel, tunnel rats were sent in to kill any hiding enemy soldiers and to plant explosives to destroy the tunnels. A tunnel rat was equipped with only a standard issue .45 caliber pistol, a bayonet and a flashlight, although most tunnel rats were allowed to choose another pistol with which to arm themselves. The tunnels were very dangerous, with numerous booby traps and enemies lying in wait.
During WWII, soldiers were known to take precious family photos (and Pinup Girl photos) and put them under clear grips on their 1911 pistols - called Sweetheart Grips.Sweetheart Grips | Stukas Over Stalingrad
