So, you thought you knew how second-hand smoke kills, right?
Well, during WWII, it did so in a way markedly different from today. On the Eastern Front, the Russians were out-gunned and crippled by Stalin’s initial poor strategizing. Their advantage, however, was in their being accustomed to both the terrain and the Russian winter. They could “disappear” into it, allowing them to successfully ambush the German troops.
So, what the Germans took to doing, was placing their non-smoking officers in the front-line, where they could detect the scent of their opponents: cigarettes, sweat and cheap perfume to fight the insects. It worked.
Second-hand smoke kills.
