The Trade Convoy is a land based unit used to establish Trade Routes between cities, outposts, and / or stations. Trade Routes generate yields or increase growth rate for the trading partners, but trade units are vulnerable to attack by Alien units or other players trying to take the resources and so the routes must be protected by military units.
