There are only four different playable classes in Earth Defense Force 6, but they all have a very unique playstyle that separates them from the rest. These classes include the Ranger, the Air Raider, the Wing Diver, and the Fencer. Each playable class has their own gimmicks, their own specialized weaponry, their own unique systems, and their own pros/cons. The Fencer, for example, is Earth Defense Force 6's 'tank class' with a lot of heavy weaponry and close-range options.
