Shooting, Tactics, or Fieldcraft.

Are you A) offensive or B) defensive? Is it a one on one? Big difference that dictates tactics. So tactics must always come first, while always assuming B). At long range this becomes the realm of shooting skills. Getting away unhurt in all this is field craft.

So,

If A) then tactics, shooting, then field craft (you get to shoot first).

If B) then tactics, field craft then shooting. (you're getting shot at).

I think it could be argued that if either a or b, as a civilian doing civilian stuff, your tactics suck…
