First off, keep the desolators near your base. They eat up infantry and there is a large group coming for your base from the start. They're paratroopers so set up a desolator underneath them and deploy him. The poor conscripts will die right when they touch the ground. These paratroopers will come repeatedly to harass you so watch the skies. The apocalypse tanks you start with will do well handling tanks that threaten your base from time to time and it is a good idea to try to level them up. Two elite apocalypse tanks can really dish out some damage. If one gets in the red, get it out of there. Let the other handle the attackers because often the enemy will try to focus on the most damage tank (wisely). I'd recommend building a service depot since you are using apocalypse tanks now - they are really expensive and you should save what you can. The small enemy base across the bridge should be your first target. A few apocalypse tanks handled it alone in my case but if you want to play it safe you could bring some infantry (desolators maybe?) to back them up. For the base protecting the white house I went all out with four V3s being protected by four apocalypse tanks, about ten each of desolators and tesla troopers and a flak track on standby with an engineer inside to get him to capture the building when it's safe. It went well for me, I beat it under par by a couple minutes. This is definitely the hardest map yet.
