Fair questions. We know is was a mix of MG42s and K98s and certainly there was a good deal of semi-aimed panic fire by the Germans on the bluffs…
But I’ll try to find the figures of medics hit in the first waves, I think it’s the majority of them. The general consensus was that the machine-guns were trained on the waterline to nail troops running from the landing craft. But that there were snipers that were raking the beach of anything moving.
You of all should know that soldiers are sensitive regarding their medics…
Artillery, Mortars and Machine Guns all work on the principle of killing everything in a particular zone - so unless the US had set up a field hospital on the beach by this stage then their use was legitimate.
No argument there.
