S.L.A. Marshall and the Ratio-of-Fire Theory: Did Only 15-20% of US Riflemen Fire Their Weapons during WWII?

“I had a feeling of the essential rightness of all.  He was dead and I was alive; it could so easily have been the other way round; and that would somehow have been right too.”  - Richard Hillary, Royal Air Force pilot, reflecting on the first German plane he shot downIn this episode we look at the controversial claim made by US Army General S.L.A. Marshall in 1947, when he asserted that less than 25% of US riflemen fired their weapons at the enemy in WWII.  What is usually called the ratio-of-fire statistic, Marshall’s thesis almost immediately influenced the US Army did undergo training reforms to ensure more of its troops fire their weapons, which have succeeded such by the Vietnam War, over 90% of troops were firing at the enemy.  The ratio-of-fire statistic had proven to be influential outside military circles, having inspired numerous social scientists to accept the notion that soldiers have an innate reluctance to kill, despite whatever training or propaganda they are exposed to.  Here we dig deeper to investigate the evidence for Marshall’s claim and explore why it has proven to endure despite the controversy and criticism surrounding it.
