Quick question about commendations

So my company only has one more commendation to complete until we get the Achilles helmet.
The commendation to complete is the road trip commendation where we kill enemy Spartans with a vehicle.
Does anyone have a strategy that will help get those kills faster (Not farming obviously).
Like a certain vehicle or a certain way to use it that will help get that commendation completed quicker?
thanks for the help.

The standalone Chaingun turret, Rocket Pod turret, and Guass turrets can help contribute to the commendation without having to risk losing a vehicle. I would say the Plasma turret, but that thing is atrocious.
