Tank used T-100 LT and T92.
If you get one of the scout maps you could probably make this with just that game alone but dont count on it. You have 5 tries to get one, I got 1 semi good one and that map alone gave me 4k spot then on the rest I did some tracking and some spotting when possible. If you dont want to risk it with scouts I would go for some fast firering MT so you can track and keep tracking. Not that hard mission. Best of luck to you
