Problems with turrets on USS Freedom

[nerexis 9]

I don't know if I'm adding turrets to USS Freedom in right way, because there are few problems with my code:

• turrets very often fall through USS Freedom model into water at spawn
• I can't make them join Resistance side, is it possible?
• when sometimes they spawn in correct position, they don't attack anyone or do anything

 

Here is my code for creation of USS Freedom and 2 turrets (Praetorian):

_carrier = createVehicle ["Land_Carrier_01_base_F",_aircraftPos,[],0,"None"];
_carrier setPosWorld _aircraftPos;
_carrier setDir 0;
[_carrier] call BIS_fnc_Carrier01PosUpdate;

_carrier enableSimulationGlobal false;
_carrier enableSimulation false;

_indGrp = createGroup resistance;
_indGrp setVariable["DisableFreezing",true,true];

// _aircraftPos is spawn position of aircraft carrier 
_turret1Offset = [30.029, 174.872, 19.751+2];
_turret1Pos = _aircraftPos vectorAdd _turret1Offset;
_turret1 = createVehicle ["B_AAA_System_01_F",_turret1Pos,[],0,"CAN_COLLIDE"] ;
_turret1 setPosWorld _turret1Pos;
_turret1 attachTo [_carrier, _turret1Offset ]; 
createVehicleCrew _turret1;
[_turret1] joinSilent _indGrp;

_turret2Offset = [-39.538, 179.126, 19.965+2];
_turret2Pos = _aircraftPos vectorAdd _turret2Offset;
_turret2 = createVehicle ["B_AAA_System_01_F",_turret2Pos,[],0,"CAN_COLLIDE"] ;
//_turret2 setPosWorld _turret2Pos;
_turret2 attachTo [_carrier, _turret2Offset ]; 
createVehicleCrew _turret2;
[_turret2] joinSilent _indGrp;

(crew _turret1) joinSilent _indGrp;
(crew _turret2) joinSilent _indGrp;
