|Age of Darkness||The Vietnam War|
Light tanks are fast and speedy armoured vehicles. Their speed and their armament allows them to take out various weaker targets, but remain easily slaughtered by antitank units and dedicated aircraft.
While not as powerful as normal light tanks, tankettes tend to be cheaper and have the advantage of being capable of being assembled without requiring Armoured Corps Doctrine. Some factions such as Italy and Japan do not require a Heavy Engineering Depot to build them, making it easier to create an armoured force to crush your foes before they can create proper tanks to finish you off.
Turretted tankettes like cruiser tanks are capable of attacking while moving.
