Ehh, this is off my jacked brain housing group memory so some stuff might be missing:
I used an earlier model of the LBT Tactical Field care med backpack, looked like this but sans PALS and a couple other bits/bobs:
outer top pouch:
TQ's, ETD's, hemcon dressings, kerlex
outer bottom pouch:
OPAs, NPAs, more ETD's, kerlex, ace wraps, coban
Clamshell'ed open:
IVs+ starter kits near the ruckstrap side, meat sewing/stapling kits in one of the lower pouches
BVM, decomp sets (Ascherman + pigsticker of a needle), and ETD/Cric kits on the other side top pouch,
Bottom pouch had ace wraps, coban, meds in the bottom pouch in hard cases (Pile velcro on the "softer stuff" ie sick call meds, Hook velcro on the "hard stuff" ie pain management/hard antibiotics/IV meds)
C-collar undone and along one side wedged, chest tube kit along the other side
Against the back as worn: multiple tarp-type emergency blankets and SAM splints stored with a single fold flat against the back
Anything else I needed more of or otherwise "isn't mentioned due to chronic CRS but would be carried" went where there was room and it made sense in the casualty care flow of "get to patient, drop ruck, start working 'off of' to 'into the bag'" as well as taking into account where you'd be in a casualty assessment/priority of injury.
All of this supplemented my worn kit which had rifle/pistol mags, 4x NPA's, 3x TQ's, 4x kerlex 4x ETD, about 20 chemlites of different colors to categorize casualties, casualty cards, gloves, shears, implement of stabbing, spare copenhagen for me or joes if checking the line, etc. Lip light on boom mic + finger light, never cared for minichems in the mouth for a light source (they taste like ass and chew funny if you have one break in your mouth

)
All the kits, specifically cric/suture/chest tube sets, etc were all forceps and associated necessities for doing a procedure wrapped up together and vac sealed in foot wide vacum seal bags so you could pop that and have everything you needed for a job right there with a "clean field" to stage stuff from for a procedure. Edge of seal pre-nicked w/ offset large tape tabs to be able to grab for opening and a second sealed area with white bandage tape labeled in sharpie of kit name and a small hole on the edge to slide in a mini chem. Pre-planned Night missions I'd pop some mini chems and slide them into the labeled areas on the more "urgent use" kits so if I had a helper they could ID what I was asking for out of my bag in lieu of me having to stop and get it myself. Always checked for any signature either ambient or under NVG's before stepping off, never had an issue.
