Kour, SR mechanics is impossible to deliver such orders with lethal ammo, even in the best intention, drone can just shoot of the arm, which will result in death. (or formally speaking delivering more P damage, than a target can accept)
The drone will join the combat in case of firefight but will not shoot. You'll be allowed to make a Pilot(1) roll, if succesful the drone will target firearms, but will not go into targetting limbs.
anyway, this will be overriden as soon as Omar or Mouse jumps in (which by the way I assume they are, from the moment you told the D1 to stay - Mouse in D1, Omar in Dobbey).
