Making soldier not captive if he has a weapon

[Morbo513 10]

Ok, I'm trying to make a mission (for personal use) where the player has to rescue a captive pilot from the SLA. I want to make a trigger or otherwise to make it so the pilot is set to non-captive if he picks up a weapon. I tried using

if (A1 hasweapon "anything") then {A1 setcaptive false}

, where A1 is the pilot, but so far all the SLA guy did was stare at me when I picked up a weapon. Do I need to enter the names of specific weapons or is there a way to make it so any weapon picked up makes him non-captive?

If it affects it at all, I am using ACE mod.

EDIT: Also, is there a way to attatch a trigger to a unit so its radius follows the unit?
