I have been studying the CoC Cruise Missile Demo Mission in order to find out how I can launch a cruise missile within a mission intro, i.e. without issuing a command as player

but the mission is complex, and I keep getting the "ObHum Sound missing" error

the unit firing the missile in COC Demo is only named in a variable, which is quite puzzling (also the demo calls functions which are not mentioned in the manual)

does it always take some time for the launch facility to initialize? or can I just pop out a cruise missile and film it?

some code sample would really be helpful. I want to upgrade a movie I made with the old & simplistic BOH tomahawks some months ago, a few days before the terrific CoC missiles got released ...
