Still a head and shoulders better than a single 4 hour physical-course with a 30 minute refresher/re-qual every 2 years [not counting 3 hours of online refresher coursework].
Although that level of training is more on par with very basic buddy-care.
That said, knowing how to re-set an ingrown toenail so it won't bleed through somebody's socks on the next march is still a nice skill to learn for the platoon motrin-man.
Military medics at their most basic levels should be able to conduct IO/IV/IA and ILS in general, as well as limited surgical methods like venous cutdowns, since they are going to be dealing with people missing arms and legs due to rocket strikes and stuff and they may not have immediately available veins for injection of saline. I can think of one incident off the top of my head where a 68W had to perform venous cutdown on a sergeant missing his arms due to a Zuni rocket IRL, and at least two others where proper training in bleeding control would have saved people's lives. These would be the people at the company casualty collection point, with a paramedic as supervising, and the people in the platoon as first point of contact for severe injuries such as traumatic amputation via long rods or severe burns caused by internal ammunition/fuel fires that can't be handled by a CAT, bandage, Asherman seal, or pre-measured analgesic syrettes that you'd find in a typical IFAK. For major trauma injuries they would be first point of contact for the wounded.
Buddy aid is used for simpler GSWs on the vest and unconscious casualties due to mine or grenade explosions, which in the grand scheme of things don't matter much since you can survive them provided you aren't hit by a piece of metal that severs a major artery or two. Dudes have survived getting hit in the neck by small arms and having jugulars cut with proper bleed control and pinpoint pressure as a form of self-care, but you can't expect an 18 year old private to do that I guess, since the guys I'm thinking of were special forces dudes in their late 20's and early 30's.
That said, basic medical training should just be standard curricula for motor riflemen in general (i.e. stop bleeding, recovery position, splinting, Asherman seals, etc.) and paramedics should be at battalion with the battalion surgeon, for ALS and initial triage, and then they are evacuated to a regimental aid point for further shipment to a national hospital (for major surgery such as severe burns, traumatic amputation, spinal injuries, etc) or a combat field hospital for relatively minor things like illness or minor injuries that could be healed within a couple weeks or days and returned to the frontlines.
I'll probably draw a medkit for Dumblan combat troops that is issued to everyone. It'll be packaged by a really austere/retro way, because Galla grows poorer by the minute to preserve its wholesomeness, but otherwise fairly modern.
