Military Medical Care in T2K

Lots of those expired meds end up being shipped to third world countries to be put back on the shelves.

I read once that during the Napoleonic Wars, if a soldier was wounded badly enough to need hospitalization, he was 98% likely too die of that wound. This improved in irregular steps (the first significant improvement being led by Florence Nightingale in the Crimean War) until the Korean War, when 98% of casualties who reached a MASH survived.
Cleanliness, supportive care and decent shelter will significantly improve the odds a casualty can survive- but take the modern gear and drugs if you can!
