Seems to me you've answered a lot of your own questions here.
The JI teaches a course designed around stated CF requirements, which, for whatever reason, doesn't include patrolling. If we wanted them to hire some tactics guru to teach parts of it, they probably would have. We didn't. There's another entire thread about tactical skills for medics, too.
In one line you say that medics don't see enough trauma in a year unless they work for a civi organization, then in the next you denigrate the medical skills of a full time ER Nurse who serves in the primary reserve at, no doubt, significant sacrifice for 19 years, as well as all other medically employed reservists. That's right, we're just the Mo, and those civi patients out there that we scrape up off the road or stitch up or heal every time we go to work have an entirely different physiology of those in the real army, so we can't possibly have any insight into how to look after soldiers when they're broken.
Your benign questions displayed a pretty high level of ignorance of the original thread, seeing as how the discussion was about the need for tactical training of medics and the medical tng of cbt arms to bridge that "middle ground", a discussion by actual, real, SME's, ie people who had taken and/or taught the course, or clinicians with a genuine interest in improving tactical patient care, and turned into a technical discussion about fluid resuscitation in the field.
Apparantly, you need NS or another solution to piggy-back Pentaspan with. Pentaspan, I'm told, even in relatively small amounts, provides a benefit to the hypovelemic patient. I didn't know that, and now I do, thanks to reading a discussion between two other experienced health care providers. Seeing as how I didn't make it to Op Med, and the info hasn't been distributed here, it's nice to find this stuff out.
Thanks to them, I'm one learning point closer to providing better tactical patient care. That's kind of the point of this discussion, to improve tactical patient care, which is something even you seem to find agreeable.
So, have you any points of professional interest to add? Know a super-ninja-tactics type who can tell us how to do it better ( a new system), or is it just a matter of more tactical training for medics (more field time and the same drills)?
