The interview stories of G.I.s from WW2, you get the impression it was under very specific conditions in ongoing daily small actions. I used to shoot with a Korean war vet who told a similar story from his time in the trenches towards the end of the three years. His group used it to lure the enemy to popup for their marksmen to pick off.
Who knows but, it crops up from interviews with soldiers. Now war stories get embellished, and the vet I shot with was in love with my Garand.
