Get 10 kills each with Tank destroyers and Mobile Artilleries
These new vehicles are available in Rush, Conquest & Tank Superiority. You will need to get 10 kills with each new type of vehicle, and it is ok to mix US and RU variants. I recommend the Conquest gamemode, and the locations of where these vehicles can be found are listed below.
SPRUT-SD (RU Tank Destroyer)
M1128 (US Tank Destroyer)
Locations: (Tank Superiority)
BM 23 (RU Artillery)
M142 (US Artillery)
Death Valley: Flags A & E
Alborz Mountains: Flags B & E
Bandhar Desert: US/RU Deployment
Armoured Shield: Flags A & E
These can be a huge pain to get kills with using the regular artillery. One tip is to get 10 kills from inside the Gunship, as this will unlock Anti-Air abilities on all Mobile Artilleries. Now just sit back from the action and tear up anything in the sky, easily getting 10 kills (compared to the normal method).
