Clan Tank

The Clan Tank is a feature added in the 17.0.0 update where clans attack an enemy fort and its defence using their tank.

Tank Escort
When on a tank escort, the objective for the attacking team is to push the tank to the base in time. The attackers can use their weapons to kill players trying to stop them, or the tank can attack itself. Tanks can be ameliorated with an array of attacks such as upgrading the main gun, turrets and/or adding gadgets.

Decorating the tank
After setting up the defenses, players can freely decorate the tank. The decorations, in which don't come from Craft Items like the Clan Fort customize the color of the tank hull and the tank tower (categorized as "Decorations"), while others are interactive decorations (categorized as "Defence"), such as the Minigun Cannon or the Tank Freezer. Decorations do not appear to serve any function, but defence do.

Trivia

 * Only leaders can change the tank design.
 * Unlike the Clan Fort, the tank never had a storage, because the Clan Storage was removed on the same update the Clan Tank was added.
 * The main gun and turrets seem to be similar to the fort artillery.
 * Tanks replaced all of the rams, except the Simple Ram, which is still used in Escort. However, tanks are never used in that game mode, like the Clan Fort as of 17.0.0.
