- "Today is a difficult day, Section. But tomorrow, we all win."
- — Salazar to Section on why he betrayed his friends, as well as his last words if the player spared Harper in Achilles' Veil.
Chief Petty Officer Javier Salazar is a member of the Navy SEALs, but also works for Cordis Die as a double agent in Call of Duty: Black Ops II, where he is a part of David Mason's team. He accompanies Section on most of his missions in the future levels of the game until he is revealed to be the quaternary antagonist of the game, revealing himself to be a mole for Cordis Die in Odysseus, where he will be either killed or detained, depending on the player's choices.
Salazar grew up in Nicaragua during Menendez's rise to power, eventually growing up to join the U.S. military. As part of J-SOC, he accompanied the team consisting of David Mason, Harper, Crosby and himself to an underground facility where they learned of suspicious activity that Raul Menendez was up to in Myanmar. Salazar also assists the team in infiltrating Colossus in Karma and Anthem in Pakistan.
During Cordis Die's assault on the U.S.S. Barack Obama, Salazar is revealed to be in league/association with Menendez, when he assists Menendez in taking over the Obama's control room first by letting him free in the interrogation room, and then by killing two guards (and Farid or Chloe Lynch). After his betrayal, he asks Menendez to spare Briggs' life, stating that the admiral is a good man, however the player is still given a choice to kill Briggs.)
If the player kills Briggs, Salazar shouts "You said no unnecessary killing!" (to which Menendez responds "I decide what is necessary!"). If the player only wounds him, Salazar thanks Menendez for sparing him, with Menendez saying he wanted Briggs to see the aftermath. As a third option the player can choose to do nothing. Doing so will result in Briggs attempting to attack Menendez, but is stopped by a blow to his head by Salazar and the game proceeds just as if you had chosen to wound him. After Menendez successfully hacked the U.S. satellite network controls the U.S. military drone fleet and just before he escapes in a FA38 fighter, Salazar surrenders without a fight after Chloe wakes up and sees the Celerium virus in the U.S. military computer and she will regain control of the U.S. satellite network by using one of the traces in the source of the transmission. (Depends of player's choice)
If Harper was killed by Farid in Achilles' Veil then Salazar will be taken into custody and never seen again. If the Strike Force missions are complete then he will survive and will stay in custody.
If Harper was killed and the Strike Force missions are incomplete or if Briggs was killed, it is assumed that Salazar will be killed by the drone fleet when they destroy the Barack Obama.
- After Harper executes Salazar, his corpse will still appear as an ally and shooting it will result in a friendly fire.
- Salazar has two M9 pistols holstered, however when he draws one of them, the M9 turns into a Five Seven.
- Salazar can be seen in the outro dancing and is seen dancing next to Harper, still wearing his SEAL uniform.
