Institute some sort of prestige system for EMS like Police Medics.
Remove Defibs, Blood Bags, & Splints from everyone except EMS and Police Medics. Only FAKs for normal civilians. (Makes lives more valuable for all factions and would lower amount of lethal force used by Police as well.)
Higher Payouts per revive depending on distance, would work almost how delivery missions work.
EMS would have to be sworn to save anyone and everyone they can. Civilians, Police, Rebels, and other EMTs.
Institute Drag/Carry options on people who are unconscious. This would allow everyone to pull bodies into cover in combat situations since lives become more valuable
