Arma3 - Create a map marker via code

This can be done in script or a trigger etc...

If you use a trigger,

We can use a condition: to check to fire when the Intel is taken.
!alive intel_z

_markerstr = createMarker ["MM_1_display", (getMarkerPos "MM_1")]; 
_markerstr setMarkerShape "ICON";
_markerstr setMarkerColor "ColorBlue";
_markerstr setMarkerType "mil_pickup";
