It is mainly used to transport infantry but it also can be used when in superior numbers in water, during which its torpedoes will sink any capital ships in a short time. Its torpedoes can hit submerged targets but the torpedoes cannot be used on land. Note that if the unit is destroyed, any infantry inside it will be lost along with it. Because the Riptide is available once an Armor Facility has been built and has anti-infantry machine guns, it is sometimes used to rush infantry to the opponent's base during the early game if the opponent's forces consists of mostly infantry.
