Kidou Senshi Gundam 0080 Pocket no Naka no Sensou

In December of Universal Century 0079, Zeon intelligence learns of a prototype Federation Gundam being developed in an Arctic base. A team of elite Zeon mobile suit commandos is sent to destroy it, but they arrive too late as the Gundam has already been launched into space. It later appears at a Federation research facility located in the neutral colony Side 6. In response, Zeon initiates a secret mission to eliminate the Gundam, but the operation fails. As a result, Zeon threatens to launch a nuclear attack on the colony unless the sole surviving commando can complete the mission and destroy the Gundam.
