Heli extraction at smoke

I would like some help to get an Helicopter to land and extract my squad where i throw my smoke grenade, is this possible?

And also another version of the same thing, either heli supprt/plane support where the smoke is.

Edit: Or any other good idea for a similar system

SOM module includes a heli transport system in it. There's also been tons of threads about helicopter extraction and insertion. As for the 'where I dropped smoke' you could play around with empty marker POS or something.

Here's a portion of a script I use to detect whether smoke has been dropped, and it returns the positon:

//init
_cpos = markerpos "center";
_radius = 1500;
_wait = 5;

//loop check
while {alive c130} do {
	_smokearray = _cpos nearObjects ["SmokeShell",_radius];
	_qty = count _smokearray;
	if (_qty > 0) then {
		//Smoke has been dropped
		_smoke = _smokearray select 0;
		_smokepos = position _smoke;
		hint format ["%1",_smokepos];
	};
	sleep 2;
};

Can you explane it Rocket ?

How do you set it up, and how do you make just one color of smoke returns the positon ?
