How to say "corps" in Japanese

Choosing the right word

部隊ぶたいCommon
nounCovers a military force, unit or squad, including corps-sized formations. It is the general word for an organized military body, so it fits when 'corps' means a fighting unit rather than a specific large formation.
その大尉たいいはうまく部隊ぶたいを指揮しきしている。↗
That captain handles his troops well.
軍団ぐんだんCommon
nounCovers the specifically military sense 'army corps': a large organized formation within an army. When 'corps' refers to this military echelon, this is the word you want; it is not used for non-military groups.
その軍団ぐんだんは戦闘中せんとうちゅう多おおくの輝かがやかしい作戦さくせんに従事じゅうじした。↗
The army was involved in a number of brilliant actions during the battle.

For the military sense of 'corps', use 軍団, which specifically means an army corps; for a broader sense of a force, unit or squad, use 部隊.
