Armadillo

"Fortified with an armored shield, this unit is prepared to spray some pain. His Submachine Gun blasts bullets at the enemy, though they have to be standing right in front of him."

- IKKI describing the Armadillo in the 1.4 Patch notes.

Overview
The Armadillo is an 190 HP armored soldier unit, effectively functioning as a Shock Trooper and Riot Trooper hybrid. The Armadillo has a Shock Trooper's style of attack (short range, multi-shot) and a Riot Trooper's armor.

The Armadillo is an interesting unit choice since it has similar armor and health as a Light Tank, so it can serve as a cheaper front line buffer. However, it lacks the firepower to destroy enemy units, cannot penetrate enemy armor, and lacks much survivability without additional ranks.

Keep in mind that the Armadillo is one of two units whose is completely ignored while under the effects of  himself. This means that damage the Armadillo sustains while stunned ignores completely and is applied directly to. The other unit with this "active-type" of armor is the Riot Trooper.
