Delete group when using BIS_fnc_spawnGroup

[1para{god-father} 105]

I am greating a group :-

_grpbuild1 = [getMarkerPos "task4a", east, _enemyCount] call BIS_fnc_spawnGroup;

When I know the task is finished i would like to delete all the men when they are dead , which is the best way ?

best to use a global name for the group, remove the _ infront of grpbuild1 and its good, unless its deleted inside the spawning script, then local works.

{deleteVehicle _x} foreach units grpbuild1; deleteGroup grpbuild1;
