Shipments

Shipments go out on their own, even while you are away — their times are checked every 5 minutes. If resources are short, whatever is available is sent. Merchants walk back, so a single run takes them twice as long as the trip to the target. You can have up to 10 shipments.

Trading post

A trading post trains no troops — that is the price for it being impossible to conquer and for foreign armies passing through without a fight. Units trained elsewhere can be sent here as support.
