That is not how I read the report. The report clearly said that the information was gained by interviewing the soldiers soon after the battle.Gawdzilla wrote:BG, the figures for random- or non-firing troops were extremely soft and based on impressions in most cases. The WWII figure was based on the number of bullets fired versus numbers of enemies killed.
Nor was that the only source. The book on killing (summary here - http://www.military-sf.com/Killing.htm) describes several other situations where most soldiers did not fire, including the Battle of Gettysberg. WWII fighter pilots where 1% of pilots shot down 30 to 40% of enemy kills. It is well known that in battle, most kills come from artillery, or bombing, not from individual soldiers shooting. Viet Nam may be an exception, since the soldiers sent there received special training to overcome the reluctance to kill.
I remember some years ago reading a report in a science journal about research on American Civil War casualties. The researchers were puzzled, because they dug up so many bullets that they calculated that each square inch of an advancing army front should have received one bullet on average. There should have been no survivors amongst the attackers. It makes sense only if you realise most of the defenders were not firing at the enemy.
I know this is counter-intuitive. Most of us naturally think that when the enemy is attacking, we will shoot back. But it is apparently not so, unless the soldiers have first had intensive training to 'brainwash' them into automatically shooting back.
