The code used for ejecting the units is:
_nul = [] spawn {
{
if (vehicle _x != _x) then {
unassignVehicle _x;
_x action [""EJECT"", transport1]; sleep 0.75;
}
}forEach (units paratroopers1 + units paratroopers2);
}
(where the groups paratroopers1/2 (all paratroopers) are moved in cargo of transport1 (Huron) via moveInCargo during initialization)
