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 describing the Puma on the 1.5 Patch page.

Overview
The Puma is second tank-type of unit available to the player, after the Mini Tank. Its wheeled nature accounts for its high defense and dodge rate. It also boasts far more HP and Armor over the Mini Tank and more importantly, is able to shield units behind it due to its Blocking type. The Puma is perhaps the first true "tank" unit available to the players, holding the front line longer than any other unit available due to its armored nature.

The Puma requires Merits to train, which requires friends in a player's friend list to accomplish.
