Future Warfare

Future Warfare is the final side challenge for Commander's Challenge, available only after all main challenges have been completed.
==Briefing==
Sorry to break this to you, but we don't expect you to succeed here. Please don't take it personally. Nevertheless, you are cordially invited to square off against all three of the Allies' commanders, who have worked out a strategy that they say you will never be able to defeat, and we believe the threat is credible. For what it's worth, in the unlikely event of your victory, our finest prototype will be yours.
==Background==
The three Allied commanders have invited the FutureTech Commander to a battle, having worked out what they claimed to be an unbeatable strategy. This time, not even FutureTech expects the Commander to succeed, though they promised FutureTech's finest prototype - the Future Tank X-1 - as a reward should the Commander win.
