Hi sorry to bring that post up, but I assume I've got the same issu :
Helicopter (full) place on the desk of USS Liberty.
Put AliveCombatSupport code in the init. of the vehicule box : this setvariable ["CS_TYPE","TRANSPORT"]; this setvariable ["CS_CALLSIGN","Seagull"];
Seagull show on the Combat Support menu as "Unit is combat ineffective" in red text.
Did try to put it a little bit higher with the Z-AXE of editor. But nothing ...
