Dance and performance has been part of almost every warrior tradition that I'm aware of. The Spartans had Gymnopaedia, Europe (along with many other areas) has numerous sword dances, the Maori have haka, Muay Thai has wai kru, modern militaries have drill, etc.
Dance appears to be a very natural and primal form of human ritual, so it's not surprising that most cultures have utilized it as a way for warriors to build confidence and demonstrate their attributes & skills.
