Vulcan jujitsu
Ramsey "demonstrating" Vulcan jujitsu
"Vulcan jujitsu" was Captain Amina Ramsey's nickname for a form of Vulcan martial arts in which Lieutenant Durga was particularly adept, a reference to Earth's jujitsu.
In 2380, Ramsey told a story of how Durga saved her team from an attack by four Borg drones using the art form. (LD: "Much Ado About Boimler")
It is unclear if this is an intended reference to Suus Mahna, or another established Vulcan martial art.
The "move" demonstrated by Ramsey seemingly incorporated a Vulcan salute.
