Protect the Chronosphere research center

Protect the Chronosphere research center is an Allied campaign mission of Command & Conquer: Red Alert. The mission involves protecting the Chronosphere and Tech Center until a vital experiment is completed (when the timer ends).

Although a base is already constructed, it is without a Construction Yard. A mobile construction vehicle with a compliment of tanks and Anti-tank minelayers are available but will have to take a considerably long route blocked by Soviet tanks in order to reach the base. The Chronosphere would be strafed by Yak-9s while the power plants would be damaged/destroyed by Tupolev Tu-16 bombers, resulting in low power. There are gap generators shrouding the Chronosphere and Tech Center, but these are completely useless as Soviet aircraft will still attack whatever unit or structure is in it anyway (they're as good as being sold for credits and power saving).

A Soviet base also exists but is without an ore truck. Nonetheless, their War Factory will still have some activity and they will receive dozens of armored reinforcements which immediately attack. The mission is a failure if either the Chronosphere or Tech Center is destroyed first.
