The squad that helps Ultraman Ace is TAC (Terrible-monster Attacking Crew), which was formed by Captain Goro Ryuh. Members of the crew were Ichiroh Yamanaka, Tsutomu Konor, Kohzoh Yoshimura, Seiji Hokuto, Yuko Minami, and Noriko Mikawa. They have access to all documented Kaiju attacks from the past attack teams and usually use these to assist them in their battles.
The 5 Ultra Brothers arrive at the Earth together in episode 1 when the two humans were revived. Ultraman Ace gives them the ring and merged with their bodies. Both soon join the attack team in fighting off the new era of monsters.
The Far Eastern Branch Base is in Yamanashi Prefecture in between Aokigahara and Fuji Five Lakes. The base's facilities are cleverly camouflaged by using the terrain and natural ostensibly, while the entrance is disguised as the weather station.
The main command room is located underground (bathroom facilities are also directly connected to the main room), it includes a library of ancient literature references, various laboratories, a shooting training field, the central atom power chamber, the hangar of large hand made missiles. A Choju radar, a variety of welfare facility buildings, a general conference building, and a research building all exist on the ground-level portion of the base.
In addition, for protection against Choju attacks, the base has been enhanced with defenses of the very best equipment, such as a large-scale field gun, and 4-twin and 16-twin rocket launchers. In spite of its top defenses, Choju and aggressive space-aliens have managed to compromise its security, leading the base's front grounds to become a battleground between the invaders and Ultraman Ace.
