Basing this off my platoons medic here in afghanistan.
The medic would carry an IFAK, location depends on SOP for your unit. All of my brigade is on the right hand side of the IOTV/plate carrier. This is so in the event he is wounded, first responders know exactly where to look. Also makes a handy rest for your elbow when you have to use your left hand for things other than supporting your weapon.
This is for use on him, because if he goes down, a joe isn't going to know how to use all the tools in his aidbag.
He also carries the rip away pouch that was mentioned earlier in the thread on the front of his thigh, not the side, cause it'd get snagged when dismounting and mounting into vehicles. It's pretty bulky.
It carries all the things you'd need immediate access to to augment what a downed soldier already has in their IFAK. A second tourniquet: chest seal for tension pneumothorax, pressure bandages, extra rolls of kerlix (you can grab the center of a roll and pull it out into a pencil shape to shove in wounds). Then he shoves a pair of medical shears into the molle webbing on the outside
of the pack.
He carries a WALK (Warrior Aid and Litter Kit) bag on mid-long dismounted movements. On mounted movements, or short distance dismounts, it usually stays in the back of his vehicle.

This is exactly what is issued. He has medical tape on each pocket, with the things we would need to reach if performing triage or in the event he goes down, written on them.
There's additional stuff added to it, IV's etc.
It's also stocked with basic antibiotics, penicillins, burn creams, ibuprofen etc, do distribute and apply to local nationals that need medical care.

The rest of his kit is exactly the same as the standard rifleman loadout.
Edit: Also, in rough, mountainous terrain that we do alot of work in, a SKED litter is necessary. It's the only litter that can be hoisted from the ground into a helicopter. Typical litters require the casualty to be placed into a landed bird. They aren't typically carried, because they can be dropped from the bird, but it happens occasionally.

I don't know how realistic you're trying to go with this, but modeling your load after that will get it down perfectly.
