Suus Mahna is a form of ancient Vulcan martial arts, and takes many years to learn.
T'Pol was trained in the arts of Suus mahna, and in 2152 tried to teach as much of it as she could to the inhabitants of a deuterium mining colony, to ward off Klingon pirates that had been harassing them for 5 seasons.
One important move she taught them, the Navorkot, was a way to evade an oncoming blade, by jumping to the side and rolling based on reading their movements to foresee where they intend to strike. (ENT: "Marauders")
Background
Suus mahna was named after Mike Sussman by writer Chris Black. In response he named Admiral Black after him.
It is probable the tal-shaya, from TOS: "Journey to Babel", is a move in Suus mahna, or that the two are related in some way.
Spock was to use suus mahna in Star Trek to defeat the Romulan crew of the Narada, but ultimately it was dropped in favor of a gunfight. This was retained in the novelization – observing him defeat five Romulans by neutralizing the strongest one first, then the second strongest, and so on, Kirk marveled that Spock even fights logically.
