How to say "troop" in Japanese

• 一行いっこうCommon
  nounFor 'troop' meaning a party or group of people traveling together, as in a touring or visiting party. It treats the people as a single body on the move.
  一行いっこうは苦労くろうして登のぼっていった。↗

  The party fought their way up.
• 中隊ちゅうたいCommon
  nounThis is the military sense of 'troop': a company-sized unit of soldiers. Choose it when talking about armed forces and their organization, not about groups of people in general.
  この仕事しごとはその砲兵ほうへい中隊ちゅうたいのだれにもできない。↗

  This job is not for any person in the battery.
• 一団いちだんCommon
  nounReally a word for a body, group or gang of people gathered together. It fits 'troop' only loosely, when it means little more than a group, so it is seldom the word you want.
  群衆ぐんしゅうは密集みっしゅうした一団いちだんとなって動うごいていた。↗

  The crowd was moving in a solid body.

Choose 一行 for a troop of people traveling or moving together, 中隊 for the military unit sense, and 一団 for a gathered body or crowd, though 一団 is a general group word rather than a precise match.
