This should not get personal. These are matters of fact that are well-documented.
In the order of your comments:
All branches of the military issued knives - millions of them. In addition to the 2,000,000+ M3's, 1.2 million 225Q's were issued - to sailors, airmen, Marines and Soldiers - in the Pacific and in Europe. Millions more Mark I's were issued, not to mention pocket knives and machetes.
The Marine Corps, in general, was "organized" and did not land formations and tell them to survive until relieved without resupply and reinforcements. One should not generalize from the four small convoys in the first month of the Guadalcanal campaign any more than one should generalize from the Army's supply fiasco in the first days of the North African campaign (where we learned the "hard way" that "top priority" should not mean loaded in the ships' holds first). Larger convoys and substantial Marine and thousands of Army reinforcements arrived at Guadalcanal in the next few weeks. The First Marine Div was relieved by an Army and another Marine division (2nd) after about four months.
I had two uncles who fought in the European Theater. They both boarded ships in the U.S. and landed directly in North Africa. They came home in 1945, having never even seen Great Britain.
Marines were also given bayonets. While in theory, bayonets were to be fixed, just as rifles were to be loaded, only on command, reality was often otherwise for combat soldiers and Marines.
If you have sources of facts to the contrary, please share.
