I couldn't agree more, with the medical as well as the riflery. I've often said it is important to rember that when using Earth, or Eurocentric History it is important to seperate cultural notions from TL.
While there is a valid point to be made there, I'd argue the entire Traveller TL scale is Eurocentric. While advancing TL in one given area could be (arguably) seen as independent of any given culture's view of history, certainly the broad TLs at the planetary or social scale of Traveller are not just Eurocentric, they're basically modeled after Eurocentric history as taught in American schools.
Trying to break away from Miller et al's TL scale is certainly do-able, but even in many non-European historical cultures (especially, say, China or during the "flowering of Islam" periods), you already run into less-than-palatable cases of "TL X in this area, TL Y in this area, TL Z in this area."
Also, even if this TL3 world is in contact with a much higher TL, I don't see the local powers that be spending their wealth on training medics, but on trying to get their hands on better weapons. AK-47s (or their future counterpart) will be much higher on the priority list for those supplying the army than anti-biotics and pain killers.
While societies certainly are known for that trait, historical societies in particular, it is also possible to imagine societies where life might be more valued. It's also possible to imagine societies basic discovery-and-knowledge propagation might be better. It doesn't even require the usual deus ex machina of offworld contact.
Going to real-world examples: The antibiotic properties of penicillin in the form of bread mold could have been noticed and the knowledge propagated and applied (for instance, if the printing press were discovered in Europe at the time the Chinese did instead of Gutenberg). To take a page from the US Civil War, a field surgeon who was boiling horsehairs for use in stitches might have noticed that those stitches tended to become infected less and tried the same on his surgical instruments and made some interesting discoveries. The combination of the two would have already been revolutionary for field medicine.
