Iranian plan B

To clear at least this one detail, I am basing on memory I have about TV docus about D-Day and the occasional read here and there, nothing systematic since I am not overly interested in WWII. But if over the years I repeatedly read and see historians claim on TV, internet and in writing that on D-Day the more unexperienced units were sent first (that must not include whole divisons, but can be the most unexperienced companies in a battalion or other most unexperienced battalion in a brigade/division), and when I had little reason to doubt that since militarily it makes sense (militarily, lets leave peacetime morals out of this since war is not peace, then this leaves an echo, a mark in my memory. And so I say that some historians say that unexperienced units got sent first.

Nothing to do with morals, its just that evidence doesn't support your claim.
