Wrruushi
this was the name of a Wookiee martial art. Those Wookiees who became skilled in Wrruushi combat were known as devastating hand-to-hand fighters, and were considered deadly at close ranges. The Wrruushi form of combat was never taught to beings of other races, since it could only be performed by the incredibly strong physique of a Wookiee. Compared to other forms of martial arts, the Wrruushi was relatively slow-paced, being focused on intensely-powerful punches and jabs that took advantage of a Wookiee's upper-body strength. The advantage of this form of martial art was that it emphasized the use of a single, heavy strike against one's opponent, rather than a combination of two or three blows.
