I have been using Arma 3's editor for a little while now but never really got serious, I know you can change an ai or player loadout by just setting it in the conditions, but what i would like to know is if there is a way to change the condition parameters on those ai and players through a trigger. is this possible?

EDIT -> i have found out how to do this with a little bit of common sense and peicing together that "this" is the unit in which is being edited. now my only problem is editing multiple units without having to code each line for each unit

You should script (trigger or sqf file) something like:
{_x add... "something"; _x setskill 0.5;...} foreach my_units; where my_units is an array of the units you want to modify, or foreach thislist if in a trigger matching with the conditions.
I can't help further with your own code.
