ForEach does not work with Move

[widget]

Can anyone answer why this ...
      "_x Move [_xc,_yc]" ForEach _array
doesn't work (none of the units move as required), while this...
      "_x SetDammage 1" ForEach _array
does (all units in the array die).

I have developed a script for making patrol waypoints vary within a specified radius each time the patrol visits them.  This takes away the precise predictability of the route (FP's Placement Radius only randomises once - at the beginning of the mission. After that, the route is predicable again).

It works well with single units, and with groups unless the leader is killed - then all other members halt, rather than continue the patrol.

I'm trying to do the same thing with an array to overcome the group problem.

Any suggestions?

For the move command use the group name

Alpha move [0,0,0]

If the leader is killed, the next in line should still follow the command and tell the group to move.
