My personal favorite combo for medics is the Fast/Dedicated Gunslinger/Field Medic route. It allows for combat, as well as healing, and once you get to higher levels (gunslinger and/or field medic) you can specialize more. Also, as said before, three levels in Dedicated gives you not only that +3 to Treat Injury, but also Faith, a great ability to have, just in case.
