Laser designator on AFV

[orsone]

I have an AFV that requires a Laser designator , and i have some questions for those that know  

I basicaly just want to use the default LD from the game.
Similar to the Kiowa , i pasted in all the references from a Kiowa .cpp into mine but...

Does the LD need any special points in the memery LOD ?

Is it possible to use the custom optics i have for the standard gun and MG , but use the default game LD optics for the LD ?

I see the LD in the weapon list in-game but it has no effect or red dot ?

Any help would be appreciated
