True. However on a percentage basis I think you will find that the Marines lost a greater percentage.
You need to remember that the “percentage” is misleading, the “percentage” removes all of the non-combat jobs that the Navy does for it’s Marines, while the Army includes both of those counts, rather than separating them.
Besides, why did percentages come up anyway? The Army lost men fighting in the Pacific alone, equal to the total WWII losses of the Navy and Marines combined, that is the history that people don’t know.
