Tick tank

The Tick tank (nicknamed "The Mole") was a light tank roughly equivalent in their battlefield role to the Titan. It looked similiar to the Black Hand light tank its design was based on, with the exception that it had a burrowing tool mounted on it's front and the turret was mounted on rails. Its crucial ability was burrowing, as it could dig into the ground assuming a vertical position, leaving only the turret and rear part visible, providing cover and protection - hence the unit's name. During the burrowing phases, the tank was defenseless, but that was a minor flaw, as the process was quick enough to avoid serious damage.

The main cannon was a relatively small caliber APDS with an explosive shell. This was enough to penetrate and damage armor of GDI walkers. However, it was less effective against infantry, as they could take cover from the shrapnel and explosions.

The tank had several drawbacks. It couldn't burrow on certain terrain types due to the tool not able to pierce the soil, and it had no anti-aircraft defense.

It was widely used by the Brotherhood of Nod, both in its deployed and undeployed state. As makeshift turrets, they were commonly placed at key choke points in defense of critical installations, such as the medical colony where Tratos was being held or its radar array. They were also used to protect advanced artillery units, who were defenseless at short ranges. GDI used a variety of counters against the tanks, ranging from simply attacking from outside the tank's range with Juggernauts or Mammoth Mk. IIs (when available), to airstrikes carried out by Orca Bombers and Orca Fighters, to simply using aggressive assaults with massed Titan formations or light infantry and disc throwers to overwhelm the static defenses.

Legacy
The Tick Tank was replaced by the Scorpion tank after the Second Tiberium War.
