队伍(duì wu) - line of people, troops, team in Mandarin

队伍 (duì wu) is a body of people arranged in a line or organised as a group. Note the neutral tone on the second syllable, which catches learners who have met 伍 as wǔ elsewhere. Depending on context it is a queue, a marching column, an army, or a workforce, and Mandarin sees all of those as the same shape.

Measure words follow the sense. A queue snaking round a corner is 一条队伍 because it is long and thin; an organised force is 一支队伍. The queue you stand in is 排队 as a verb, so 排了一条队伍 is the natural way to say a queue formed.

The trap is assuming it covers team in the sports sense. A football team is 足球队, and the project team at work is 团队. 队伍 for a group of people implies size and organisation, often with a whiff of the institutional about it, as in 教师队伍 the teaching profession. Reach for it when you mean the ranks rather than the eleven on the pitch.
