Going back to your point in regards to WWII I would put it this way 100% of Marine Coprs divisions engaged in amphibious operations including the most ciritcal ones (read also Guadalcanal, Saipan, Iwo, etc). What percent of Army divisions engage in amphibious operations? I won't hesitate to admit that Inchon was also half Marine and half Army but the LEAD was Marine Corps just as the LEAD in almost all Pacific Operations was Marine Corps,
That’s nonsense. Are you just going to outright claim the Pacific war consisted of only the central Pacific line of advance now? The upper Solomon’s- New Britain-New New Guinea - Philippines axis was fought almost completely with US Army and British Commonwealth troops, and saw more amphibious landings then any other campaign in the war. Marine participation was limited to a raider battalion in New Georgia, alongside. five US Army divisions, while the 3rd Marine division went ashore in a remote part of Bougainville against opposition numbering in the dozens, only to be replaced by US Army divisions before the Japanese could even mount a full scale counter attack.
given the percent of available combat arms they represented this entails a disproportionate committment to amphibious operations.
Percent of available arms? After the end of 1942 the US Army consistently had over three times as many divisions in the Pacific as the Marines did, and at no time did Marine divisions outnumber Army units. This totally ignores the vastly greater combat and logistical support forces the Army brought with it too. The Marines had virtually no corps level troops, and couldn’t even dream of army formation level support.
Stating that the Army committed to major amphibious landings and therefore specializes in it is like saying the armored relief columns in Somalia were participating in SpecOps missions and are therefore specialized in them.
The US Army mounted more amphibious operations, its troops were required to backup numerous Marine landings, such as at Guadalcanal, Bougainville, Saipan, and it made all the largest landings by far. Yeah, the Army damn well could do an amphibious operation every bit as well as the Marines, and its ability to land and support a whole mechanized Army over a beach, vs. 1-3 Marine divisions with single tank battalions and towed artillery, is simply unmatched. The only inherent marine advantage was amtracks, and those early amtracks only matter when you have to climb over coral reefs.
The largest pure Marine Operation, and largest Marine operation period, was Iwo Jima, with two assault divisions and a third landed in support behind them. In contrast the US Army commitment for Operation Torch in 1942 was five divisions strong, about two divisions worth landing as assault troops including airborne forces. Husky was a six division landing for the US with 3 division in the assault force plus a Regimental Combat Team of airborne troops. Normandy was bigger still in terms of Army commitment both to the assault force and the overall force landed over the beach.
