Spawn a unit when side arrive

[puzzola 10]

I created a mission with too much units.

So I would like to spawn some group when some west side unit is in range.

I have no idea how to.........

I understand to make a trigger with west present, but don't know how spawn groups in consequence.

The groups then are mixed terrorist so have I to script something for the leader or member for member?

Please if you can past a script "as to", cause i start from zero really.

Thank you

Too much script for me, there are other effects in this script and I can't sort the right one.

Thank you
