How to spawn rebel citizen medic

You can modify existing citizens to become medics after you've already spawned them.

To make and individual citizen a medic:

Mouseover them with the crosshair and enter ent_fire !picker setmedicon into the console.

To make all citizens medics:

Optionally, spawn new citizen(s): npc_create npc_citizen

Toggle them to all be medics: ent_fire npc_citizen setmedicon

To toggle groups of citizens to be medics, or to toggle individual citizens to be medics without mousing over them:

You can assign citizens (or individual citizens) to custom groups when you spawn them: npc_create npc_citizen whatever_group_name_you_want

This allows you to easily modify specific citizens that you've spawned: ent_fire whatever_group_name_you_want setmeticon

Alternate example: npc_create npc_citizen medics ent_fire medics setmedicon

Another example: npc_create npc_citizen jack ent_fire jack setmedicon
