I get some trouble with ArmA 2 OA backpacks script commands.
I am not using any addon. I am running 1.60 patch.
Tried this in the editor:
this addBackpack "TK_Assault_Pack_EP1";
(unitBackpack this) addMagazineCargo ["30Rnd_556x45_Stanag",6];
No result, my unit does not have backpack in his loadout.
