How would you say the following in Korean?

Combat :

1) If used as a noun, "ssa-oom", or "kyuk-too"

2) If used as a command, like in "Begin fighting", "ssa-wuh"

Boxing:

"kwun-too", (you can also use the English word, it's common among most Koreans)

Kick Boxing:

there's no specific Korean word substituting this word. You can simply say "kick boxing"

Self defense:

"jagi-bhang-uh", or "hoe-shin"

Powerful and balanced self defense:

"kang-ha-go, ahn-jeung-dwen, jagi-bhang-uh"

Powerful and balanced combat:

"kang-ha-go, ahn-jeung-dwen, ssa-oom"

Hope it helps!
