You can use this script: call it "eject.sqs"
------------------------------------------------------------
_grp = _this select 0
_vehicle = _this select 1
_aunits = units _grp
_i = 0
_j = count _aunits
#Here
(_aunits select _i) action ["EJECT",_vehicle]
_i=_i+1
~1.4
?_j>_i:goto "Here"
exit
=======================================
exec in your trigger like this:
[mygroup,heli1] exec "eject.sqs";
[mygroup2,heli1] exec "eject.sqs";
[mygroup3,heli1] exec "eject.sqs"
to name your group use this in the leaders init field:
mygroup=groupthis
mygroup2=groupthis
etc......
hope this helps you out
