regiment, party, company, squad
隊 centers on an organized group of people acting together: a regiment, squad, company, or party. The common thread is a structured unit with a shared purpose.
隊 combines ⻖ (mound, hill) with 㒸, which likely contributes the sound and may relate to falling or grouping. The exact historical development of the right component is uncertain, but the character has long been associated with military units.
The left side ⻖ looks like a hill or rampart, and the right side 㒸 resembles a group of people with a leader. Picture a squad lined up on a hill, ready to move as one unit.
For タイ, imagine a squad tying their gear together before a mission: tie -> タイ, and the whole regiment is tied into one organized group.
