Kidou Senshi Gundam: Operation:Troy  

Mobile Suit Gundam: Operation:Troy, Mobile Ops: The One Year War, 機動戦士ガンダム OPERATION:TROY

Gundam Operation Troy begins with Earth Federation's colonists fighting for their freedom against The Federation. Due to advanced electronic countermeasures (ECM), sensors and communication systems are rendered useless, leading to the development of new weapons known as mobile suits. These powerful machines, capable of hand-to-hand combat, revolutionize warfare by allowing direct contact between soldiers on the battlefield.
