If you have a cloning vat build some Crazy Ivans and either conscripts or dogs. Plant a bomb on your dogs or conscripts using the Crazy Ivans. Then put them in a flak trak. Send them into an enemy base to watch them explode. You can even put a bomb on the flak trak to make a demolition truck. This cheat works best if you get several flak traks and iron curtian the with the men inside, for you can then strategically place the flak traks to put the enemy out of action, especially if you target the ore refinary, war factory ETC.
