Why won't the artillery guys fire?

[SRBuckey5266 3]

	//rocket artillery
	_c = 0;
	for "_x" from 1 to _numArty do {
		_arty = createVehicle ["MLRS", [(_pos select 0)+(_c * 24),(_pos select 1)-86,(_pos select 2)], [], 0, "NONE"];

		_driver = (group player) createUnit ["RU_Soldier_Crew", _upos, [], 0, "NONE"]; _driver moveInDriver _arty;
		_gunner = (group player) createUnit ["RU_Soldier_Crew", _upos, [], 0, "NONE"]; _gunner moveInGunner _arty;

		[_driver, _gunner] join (group player);
		_c = _c + 1;
	};

Above is a part of my code that spawns artillery men. However, whenever I command them to fire at a position.....they simply look at the target and DO NOT FIRE.

Why is this? It's in multiplayer.

EDIT: Nearly everytime I tell them to fire at a specificed position, they'll say "I'm on it", look at the target, and then the turret back. ("Engage" on the unit icon shows up for a split second than switches to "Ready") :/...

I'm manually telling them to fire on something as they are in my squad.

I guess the game doesn't support it?

ive never used the arma artillery without code but i am pretty sure you have to link the artillery gunners or batteries to the artillery module
