Let me know if we can't duplicate the code from the CH53 addon in the
file ch53_monitorSFX.sqf. If that's the case I will use an #include
instead, since the code that kicks and kills players out of the vehicle
goes at the bottom of the file anyway.
Needed to add it to variables.sqf lists.
@icomrade - Any reason FireBarrel_DZ was removed? I think we still need
it, since it is an epoch buildable class, unless we merge it with
Land_Fire_barrel.
