So, here is the problem, im editing a mission on Arma 3 (EXILE) editor and faced this problem.

i spawned on the editor some aircraft carriers, and destroyers with its guns well placed around the map to shoot players that go to far in te map down. So i spawned some centurions, praetorians and stuff like that with its crews. I want this to shoot anybody that comes close to the ship, but i want them to ignore the admins and, if its possible, anyone that is on their group.

is there any way for me to make the bots ignore some players by the UID, and even better, ignore all players on the group of this specific UID? 

I searched a lot before get here, because i don't wanna bother. but the closest that i got is  using the comand "forgetTarget" on the unit init. But with this i need to force the admins to use a specific playable slot when loggin in and don't allow anyone with other UID to join on these slots. 
which i don't know how to do as well.

if you guys can help me solving this problem in any of the 2 ways, i will thank you for ever. =D
