Sentai

In Japanese, sentai (戦隊) is a military unit and may be literally translated as "squadron", "task force", "division (of ships)", "group" or "wing".

The terms "regiment" and "flotilla", while sometimes used as translations of sentai, are also used to refer to larger formations.

The term was used during World War II by the military of the Empire of Japan for Imperial Japanese Army Air Service (IJAAS) and Imperial Japanese Navy Air Service (IJNAS) military aviation units equivalent to a group or wing in other air forces.

Sentai in the Japanese Navy were prescribed by the document Naval military command No.

Paraphrased, they were defined as follows: The Super Sentai Series (スーパー戦隊シリーズ, Sūpā Sentai Shirīzu) is a franchise of Japanese tokusatsu television dramas produced by Toei and TV Asahi that uses the word sentai to describe a group of three or more costumed superheroes who often pilot fictional robotic vehicles to fight kaiju.
