Where did you get that idea? The two division that landed on Omaha were the 1st Infantry, a regular army unit, and the 29th Infantry a National Guard unit.

Subsequent question: I've heard that Allied generals purposely made sure that the vast majority of the troops who spearheaded the D-Day invasion had never experienced combat, because if they had, they feared the experienced troops would be less likely to advance towards the entrenched German defenses? True?

I read a history of the U.S. Army Rangers which said that the Rangers were supposed to spearhead the landings but they were late, this caused regular army units to be the first to hit the beach.
