You are correct about not needing military training for this. You can go to any shooting range in the US on a Saturday and see some pretty good shots from guys who never served in the military.
The shooter doesnt need the military for the shooting, true. However, the excape and evade procedures would come ONLY from the US or Isreal.
This guy is shooting at people literally over the heads of cops, and getting away clean. This aint no civilian.
