Combat Medic Archive

I am a Master CM and a Novice Doctor and recently gained the abiltiy to use as well as have the abiltiy to use Enhancements. Do I need to use my skill points in the other doctor trees to have enough medical use to actually use buffs and reviz?

you should be able to use revive packs with your base medicine use skill but if you want to use enhance pack Ds (the only ones worth using) you will need expert medicine knowledge

Reviving is a master surgeon skill. So, you need all the wound treatment skill boxes.
