Hi,
I just finished watching the two episodes of “The truth about killing”, which discusses the natural tendency of humans not to kill in combat and how military science is overcoming that.
Episode 1: http://www.youtube.com/watch?v=2vlGR7S2wcI
Episode 2: http://www.youtube.com/watch?v=m6jrRqGwtB8
According to this documentary, in WWII, only 2% of soldiers actually shot their guns and aimed for the enemy. Most shot without aiming and many did not even shoot at all. The reason is that in danger situations our “animal part” of the brain takes over, which instinctly says we shouldn’t kill our own species but fight side by side against our natural enemies. (In fact, so is argued, historically military uniforms were meant to be very visible and awe inspiring, with the goal of deterring, not killing, the enemy.)
Out of those 2% who did kill, half of them were sociopaths, defined as not having a different reaction to seeing violence vs seing positive stuff like food and girls. The other half were non-sociopathic killers, and military science has trained their soldiers to become like that ever since.
This training, as seen in episode 2, conditions soldiers into killing without thought by gradually making their shooting practice more realistic. Soldiers are sent to battle after they become accustomed to the act of killing. What modern science didn’t solve, however, is the psychological effects that occur after the killing - when the soldiers start thinking about what they did (and have flashbacks to horrible sights they saw).
The documentary states that nowadays 95% of soldiers kill from close distance.
Other than discussing the “progress” in close distance infantry killing, the documentary also discusses how aviation and missile technology fit in the ever existing move to more long range killing to lower the psychological burdens. So we went from bare hands => rocks => small knife => bigger knife => swords => archers => pistols => … => planes
All in all a very interesting documentary that indicates that the Hobbesian Jungle theory does not hold for 98% or 99% of people. In my opinion it clearly demonstrates the dangers of outsourced, impersonal violence.
