The source knife for the design is the Marbles Hunter from the turn of the century. Plenty of makers copied it and it was the accepted standard for woodscraft when camping outdoors. Those same skills were necessary for a lot of troops living in the field - literally setting up shelters from existing vegetation as part of their fighting positions. Infantry lived in their foxholes, moved, and set up again. Warfare is far more urbanized and mechanized today - the average soldier gets by with a Swiss Army knife at most.
Actual combat with the knife hand to hand is so rare the stories number infrequently in records, although too frequently when the provenance of the story teller won't be questioned.
Be advised nobody used them to open ammo crates or take the end off a 55 gallon drum. There is a remarkable amount of myth about combat knives largely perpetuated by some who never served and others who never served in combat. For the most part large knives are closely controlled and usually not allowed for garrison use and can be highly restricted by the unit commander as he sees fit.
Taken as a woodcrafting blade, they chop brush, cut roots, and help fashion camouflage and shelter. They can cut up small bits of wood for a fire for those allowed to do so, not in combat. Cold camps are generally the rule in hostile territory, and you train like you fight.
For the most part a soldier in the field counts every ounce of dead weight and large knives have to factor in with a high return for the individual for him to retain it. With up to 85 pounds of other gear issued to carry in the field, a one pound sheathed knife taking up space on the pistol belt is uncommon today. In warm areas far from normal shelter it's a valuable aid, but for the most part many more carried a small folder and it sufficed.
Case in point, they sell far more Navy SEAL issued knives than get issued. Thousands more. Tens of thousands in some cases. The public enjoys the myth of the fighting knife, the soldier, not so much. Things are pretty hard if they need one.
