"Active Raid" (Japanese: アクティブ・レイド, Hepburn: "Akutibu Reaido") is the title of a Japanese original net animation (ONA) and subsequent television anime series produced by Actas and directed by Toshiyo Shinohara. The story revolves around the "Special Vehicle Unit 1", also known as "Kanji", which uses powered exoskeletons called "Machineroids" to fight against criminals who use "Mode Lockers", people with the ability to solidify matter with their minds.

However, I could not find any specific information about an "机动强袭室第八组" (Active Assault Room Eighth Group). It's possible that you may be referring to a fan group, a special unit within the Special Vehicle Unit 1 from the series, or perhaps a different organization altogether in a fan fiction or similar context. If you can provide more details, I might be able to assist you better.
