The main goal of Riot Force 6 is to train the Forwards, and at the same time, stop Jail Scaglietti from obtaining all the Relics. Riot Force 6 has faced heavy criticism from other branches of the TSAB because of the fact that their captain is Hayate Yagami, owner of the Book of Darkness, and a former criminal. Riot Force 6 is also criticized because they have Hayate, Nanoha, and Fate on their team, and normally such powerful mages would not be put in a single section to spare the time-space continuum the enormous strain created by their magical activity. To address the latter problem, Hayate, Nanoha, Fate, Signum, and Vita all had powerful limiters placed upon them until the very last stages of the JS Incident.
At the end of StrikerS, Riot Force 6 was disbanded because with Jail Scaglietti defeated, there was no reason for its continued existence.
The Riot Force 6 has been reassembled again under the name Special Duty Section 6 in Force, reuniting most of the former members (in addition to new ones), in order to deal with the Book of the Silver Cross Incident and the Hückebein family.
A running joke among some parts of the Nanoha fandom is to refer to Riot Force 6 as "Hayate's Lesbian Army", because of the overwhelming percentage of its members being female and a majority of them indicating a possible attraction to another.
