The Monster Attack Teamモンスターアタックチーム (怪獣攻撃部隊, Monsutā Atakku Chīmu, Kaijū Kōgeki Bu-tai), abbreviated as MATエムエーティー (マット, Emu Ē Tī, Matto),has the mission of protecting the public from Kaiju attacks, and investigating bizarre anomalies.
Belonging to the Earth defense organization of the United Nations, the Monster Attack Team was formed in order to kill the monsters that were awakened by extreme weather events and phenomena of the earth.
They have a headquarters in New York as well as Japan, where they have a ground base in Kanda Nishiki-cho, Tokyo, and a submarine base in the deep seabed of Tokyo Bay. In addition, they also owned a space station.
The ground base and submarine base are connected by giant pipework, to move in the air support. Related weapons are housed in the sea base. In the last episode of Return of Ultraman, Alien Bat destroyed a large part of the base. It is unknown what happened to the support members, but the base begins to be rebuilt.
