Order of Battle: World War II

There is an unfortuneate truncation of the achievement description due to string limits. The full description is actually:

Accumulate 8 tank class units during a campaign game, each with at least 2 kills. Difficulty level III or higher.

So don't attempt on difficulty I (one). It needs to be III (Major).

Most importantly, contrary to the description - you need to do this in a single campaign scenario. It's not cumulative at all.

So in one scenario, have eight tanks each get 2 kills. I did it in Blitzkrieg: Fall Rot scenario. With a lot of micromanagement it's ok. Keep a little list of your tanks and how many kills they've had. The pill boxes are great for getting easy kills without taking damage. Use Stuka's (I had 3) to soften up and support against counters.

One final thing to note which may help - even if you lose a tank after it gets 2 kills, it still counts. You can also reform deceased units if need.

Good luck!
