"If your comrade is being defeated, you should see it as an opportunity. Rather than standing in the way, you should stab the enemy in the back. And if the enemy is so far above your level that you cannot even manage that... then you should let your comrade die. That is the way of the Onmitsukidō." - Suì-Fēng The Onmitsukidō (隠密機動, Secret Tactics, called the Stealth Force in the English dub), also called the Secret Mobile Unit/Corps, Special Forces or Covert Ops, is the second largest organization that Shinigami join, and one of the three main branches of military in Soul Society.
