Most units have certain skills that make them special in combat. Here is a list of them and which unit has what skill.
The dash skill allows a unit to attack after it has moved during its turn.
Units with dash
If a unit with the "Escape" skill attacks another unit and the attacker is still alive, then it is given the option to move once more, even if it already moved earlier. (Ex: A rider moves to attack a warrior, the rider attacks the warrior and kills it, the rider is given an extra turn to move.)
Units with escape
Allows the unit to traverse on Water and Ocean after moving onto a port. Upon disembarking, the unit returns to its land form. (Navigation must be researched to travel on Ocean, regardless of the unit having the Carry skill.)
Units with Carry
Scout allows the unit to explore a 5x5 radius instead of 3x3.
