The military keeps betting on what it can control, not what actually wins. Takagi built the Dorvack Team because he knew transforming machines would matter when the aliens came, but he's fighting two wars at once: the one in the sky and the one in the hallways of command. These kids prove themselves through machines that shouldn't work, in a 1983 show that understands the real enemy of victory is the bureaucrat who needs to be right more than he needs to win. The transformations are sharp, the politics are honest, the aliens are just the deadline. By episode twelve you stop waiting for the plot to turn and realize it already did: the Dorvack Team isn't trying to save Earth from invasion. They're trying to save the future from people who learned nothing from the past.
In 1999, a vast colony ship carrying the Idelians, wanderers of space for over ten thousand years, reaches Earth with its energy nearly spent, and an alien force lands at the foot of Mont Blanc. Earth's defense forces strike back but cannot match the enemy's powered armor. Colonel Takagi formed the Dorvack Team and its transforming Variable Machines for exactly this moment, yet military leadership has chosen to trust powered armor infantry instead. Young pilots Masato, Louie and Pierre set out to prove their worth in all-terrain machines, a jeep, a tank and a helicopter, that transform into robots. As the unit rises through the ranks, they discover again and again that real battles rarely play out the way they do in films. The result is a mecha action series with a sci-fi invasion at its center.
