the.com/troop

A group that moves together, usually because one person refuses to admit they're lost.

means A group of people, animals, or soldiers moving or gathered together as a unit.

from From French troupe, itself from Old French trope ('flock' or 'band'), which traces back to Late Latin troppus, meaning 'herd' or 'flock' — a word possibly related to the Germanic root behind 'thorp' (village), suggesting a cluster of beings gathered in one place. The military sense of 'troops' as soldiers emerged later, the word marching from barnyards into barracks.
