Puma

"This wheeled tank is really speedy and therefore harder to hit. It’s short to mid range and requires direct line of fire, but also carries a Light Tank Gun with an infinite supply of ammo for delivering infinite amounts of pain!"

- IKKI, per the 1.5 Patch notes

Overview
The Puma is the second tank-type unit available to the player, after the Mini Tank. Its wheeled nature accounts for an relatively high Defense. This unit also boasts far more and  than the Mini Tank and more importantly, is able to shield units due to its Blocking type. The Puma is perhaps the first true "tank" unit available to players, holding the front line longer than any other unit available at early levels due to its armored nature.

The Puma is similar in strength to the Light Tank. It sacrifices and  for more Defense, as befitting its "wheeled" nature. However, the Light Tank can research the ability Machine gun at Rank 5, allowing a more accurate attack. Also the Puma is unique in that its damage does NOT increase from Rank 5 to Rank 6.

The Puma requires to train, which can be hard to obtain for lower-level players with few in-game friends.
