Why weren't Marines chosen for Normandy?

It's friendly inter-service rivalry. Don't be an idiot.

Your immaturity knows no bounds does it....

I hate to break this to you but you're not high and mighty. There is no Soldier, sailor, Airman, Marine or Coastie, former or present, whom you are better than. You like to think that you have achieved some level of social superiority but I assure you, you havent. Enroll yourself in a good therapy program... there are many systems that can help you overcome your narcissistic tendencies. It wont be easy but, if you rely on your training, you'll find the determination you'll need to correct this stubborn character flaw. Best of luck to you, Chris. We're behind you all the way.

Except you. I am better than you as are most here. I have achieved a small amount of social superiority over you at least, but don't worry, I and the rest of the men will protect you...good luck with conquering you delusions my little friend.
