Arriving at "the 14th", Kat poses as her past self in Vietnam to keep Sator alive until the Tenet forces in Stalsk-12 recover the Algorithm. They use a "temporal pincer movement ", with both non-inverted and inverted troops making a diversionary attack so the Protagonist and Ives can steal the Algorithm before detonation. Sator's henchman Volkov traps them in the hypocenter. Calling from Vietnam, Sator explains the antagonists are trying to escape the effects of climate change. As Volkov is about to execute the Protagonist, an inverted soldier with a red trinket appears and sacrifices themself, enabling the Protagonist and Ives to escape with the Algorithm just as the hypocenter detonates, which is also just when Kat kills Sator.
