The US part of Operation Neptune was, of course, Omaha and Utah. Omaha was the meat grinder, within 10 minutes of landing the leading companies were inert, every officer and sargent was KIA or WIA. Bradley came very close to abandoning the beach. The toll was 5,000 killed.
Utah was a near perfect success due to landing errors, the currents had pushed the landing craft far to the SE and the 101st paras had also landed in the wrong spot. The two wrongs added up to a right and the landings were almost unopposed while the 101st had seized all the beach exits. The toll was 197 killed.
Eleven other countries were involved roughly 156,000 men altogether with about 12,000 KIA. No honor is to great
