How to say "shoot-out" in Japanese

• 決闘けっとうCommon
  noun, suru verb, intransitive verbCovers 'shoot-out' only in the sense of a duel — a prearranged, often formal one-on-one confrontation. For most shoot-outs it is really the word for 'duel', so choose it only when that duel nuance fits.
  西園寺さいおんじは決闘けっとうに勝かつと思おもっていたのに負まけた。↗

  Kyouichi Saionji, who he supposed would win the duel, has lost.
• 銃撃戦じゅうげきせん
  nounThe natural choice for an actual exchange of gunfire: a gunfight or firefight between police and criminals, gangsters, or soldiers. Use this for most 'shoot-out' senses involving real shooting.

For 'shoot-out' as a mutual gunfight use 銃撃戦; 決闘 is primarily 'duel', so it fits only when the sense is a formal or agreed one-on-one confrontation rather than a battle.
