After taking a stand against Command for better warfighter health, BRAVO is forced to the sidelines and eventually sent to Sweden on an underwhelming assignment. Lieutenant Davis is picked by Admiral Rivas to lead a new spec ops initiative.

BRAVO finds themselves at the scene of a terrorist attack in Sweden and Jason survives a close call. Lieutenant Davis gives her new unit an ultimatum, and a family member surprises Drew and issues a mysterious warning.

Lieutenant Davis and Captain Walsh send BRAVO to Thailand to partner with the DEA on a joint-task force focused on the fentanyl trade. The goal is to intercept a cargo ship and acquire intel that details the Chinese government's involvement. Drew is assigned to BRAVO full-time despite his objections and a journalist later questions him about his family's history. During the mission, Drew goes rogue and makes a decision that jeopardizes everything.

BRAVO targets a factory in Myanmar that the DEA has tied to China and fentanyl production. Lieutenant Davis wants the team to pull intel and destroy the plant. Jason vies for a safer plan, and some on the team begin to question his decisions.

Even the closest of brothers fight eventually. Tempers flare during a surveillance mission in Malaysia. As the team sets up camp in scorching hot temperatures, grievances are aired and Drew finally reveals why he's been so closed off.

BRAVO's next mission is to capture Jun Yilin in Cambodia, but they'll be without their leaders. Ray is pulled into diplomatic negotiations and Jason travels home to help his son recover from surgery—a task that takes a dramatic turn for the worse.

BRAVO's back together and sent on a mission to verify concerning intel that links China's drug trafficking to a potential coup in Honduras. Before leaving, Jason, Ray and Drew all struggle with something personal, resulting in a volatile dynamic.

BRAVO finally finds some fentanyl, officially linking Nazario to the smuggling operation. Despite instructions to keep a low-profile, Jason destroys the fentanyl and kills all the guards. Later, the team makes a shocking discovery at Nazario's camp.

Does war always have the last word? Jason wrestles with guilt and searches for closure in Afghanistan. The Decker investigation comes to a close, Ray starts his new chapter and the new-look BRAVO jumps right into the next mission.
