Battlezone Earth

After a B1 bomber loaded with nuclear weapons collides with a UFO, the spacecraft crashes in the Ukrainian mountains on the Russian border. A team of soldiers from the USA is dispersed to retrieve as much information about the spacecraft as possible and then destroy the vessel. The race is on when Russia sends a special forces team to retrieve the spacecraft, but a battle ensues when both units arrive simultaneously.
When Aliens from the downed spacecraft appear, Russian and American troops are forced to unite forces to defeat them.
