Road rage (20G)

Destroyed 10 Blackwatch tanks, APCs or helicopters using a single hijacked tank or APC.

This can be a tricky achievement if you are playing on hard as you cannot leave the tank at any time for this achievement. The best way to do this is to hijack a tank in the Yellow Zone since there will be very few rocker launcher troops there. The main thing is to keep an eye on your Radar and try to get whittled down slowly by small arms gunfire. Once you have your 10th kill the achievement will pop.

Note: It does not have to in Alert or attacking you for it to count as a kill.
