Chosen answer: Because they would be the ranking soldiers, and accustomed to being given orders. Being disciplined, they would obey Quintus without question. The legions would necessarily have soldiers assigned to following orders at different times, similar to how a captain would give an order to a full room, and the first mate would be the one to carry out the order.
