Right now, it's quite hard to lase a target or track it because of the UAV movement, especially when it's circling around somewhere.
I suggest adding a button that lets you lock your view on a stationary/mobile target.
Here's an example from Mando Missile from A2, which did it greatly:

(watch until 2:37)
another thing: Drones should remain stabilized on a target if you release controls from the turret, so that if you switch to a guided launcher(MLRS, helicopter, etc..) or if you just decide to manually fly the drone, it will remain locked and keep its laser shining if it was previously enabled.
