I had an Uncle that served as a Marine in the Pacific during WWII.  His preferred weapon of choice was a shotgun to shoot up into the trees with.  You might ask why would he want to do this.  Apparently the Japanese snipers would climb to the top of the trees and tie themselves to it.  So often the Marines would hear noises up in the canopy but couldn’t see what was making it.  So the shotgun was the best weapon for this situation.  Thou he did joke he shot a lot of monkeys also, after all it was a shoot first ask question later situation.  This Uncle actually owned a Cabin In The Woods, lucky him.
