Retroactively armchair quarterbacking here, but it doesn’t seem like a really great strategy to send thousands of people to be targets for the purpose of using up the enemy’s bullets. If it wasn’t for the sheer number of people that went ashore, they might have not made it. The natural selection component was that the men who were killed were more representative of the masculine nature of males. In the long run, bravery would be reduced among a population group. You could see how social engineering could be accomplished using wars.
Tremendous slap in the face to all those who involved in the D-Day operation especially those who survived, and apparently to you only the masculine males died. There is no less bravery today than there was 80 years ago on and above those beaches. You live and thrive in freedom by those who both lived and died there and you have the absolute gall to post your comment. I bet you didn't know that the Air Corps actually suffered the highest casualty rate during that operation. Now piss off.
It may have been a great strategy in as much as the enemy would think it an unlikely one.
