By 2001, virtually ANY wound has the potential to be fatal, even something like a simple scratch that IRL, you'd probably just clean out with hydrogen peroxide, and put some Neosporin and a large bandaid on and never bother going to the doctor for. By 2001, something like that , which IRL we'd consider minor or even trivial, could easily result in an amputation or even death from sepsis. Many bullet wounds that would receive prompt attention IRL could easily result in maiming or death. Minor illnesses could weaken someone's immune system just enough for something more severe to get in, something that IRL would probably be stopped with some over-the-counter medications and extra fluids and a few days of laying around watching TV quietly and sleeping.

Like before about 1943 or so, the biggest killers on the battlefield are again going to be infection, illnesses, and sometimes, the result of botched medical care by the relatively unskilled or doctors in over their heads without modern medications, equipment, or even proper medical procedures that went wrong due to doctors trying to do relatively primitive analogs of procedures that were state-of-the-art four years before.
