Adding code to objects

[Halmeth]

Hello guys, I'm having some issues trying to add code into an init unit in the kp_objectInits.sqf

What I'm trying to do is adding a 3d sound in a blufor unit built from the KP UI.

Specifically I'm trying to add this code into this rhs unit:
[ ["rhsusf_usmc_marpat_wd_squadleader"], { _this say3D [ "radiochatter", 25, 1]; } ],

So far is only working when that unit has been already built and being left in the map and is not recruited or built by admins or players...

Also it works in vehicles but not in active units...

Thanks for reading!
