Smity draws an assault rifle to secure the nuclear missile. Europol officers do not use firearms. Vo should have taken her place.
The FBI is under the Department of Justice while General Finley is from the Department of Defense. There is thus no rationale for Finley to order or call upon a FBI Team.

General Finley's role changes once more. In The Secrets She Knows (2021), he ordered the team to find a missing DOE official and ordering Forrester to stop finding his mother. In Crestfallen (2022), he oversaw the defection of a Russia spy. In Copper Pots and Daggers (2022), he told the team the ex-Marine was a NSA agent. Now, he's ordering the team to retrieve a nuclear missile. He has no jurisdiction in these roles and should have only one responsibility.
