You objective is to seize a nuclear research facility.
In this mission you key units will be twin blade helicopters. You start off by builing as soon as possible a solid defensive line of tesla defense towers. While you do this you should be building multiple airbases to parallelize production of attack helicopters.
After you have some helos go on the offensive. As soon as your helos clear units and defenses from the enemy base drop a helo with engineers to take over the structures. Then add tesla defense towers to those positions. Continue mass production of twinblade attack helos and you should be going through their defenses without a problem.
When you find air defense towers bypass them and hit the energy production facilties until the air defense towers are out of power before destroying them.
Once you send an engineer to take the research facility make sure to station a large combat force around the facility. You have to fend of the allied attack. In my game I just rushed the allies and cleaned their base with around some 40 twinblade helos. Make sure to airlift base expansions to the conquered areas where there are mines, so that every time you clear the alies out you are able to build refineries as well as tesla defense towers around the refineries.
