X66-Mammoth Tank


This mod was originaly designed to be in Arma1.

Acting on the orders of Joseph Stalin, Soviet engineers created the Mammoth Tank, the heaviest tank ever produced in the Red Alert conflict, to counter the increasing threat of the Allies latest tank. The Mammoth was armed with two 120mm cannons and twin anti-infantry and anti-aircraft Mammoth Tusk missile pods. An atomic generator powered the enormous vehicle. Mammoth was extremely heavy armored, it was also very slow. It was truly the last word in conventional vehicle technology. The enormous chassis was supported by a pair of treads on each side. The turret was plugged into the hull with a relatively thin screw-like extension. There is no large turret well and the turret is a self-contained module with crew transfer being possible between the turret and hull. The turret aiming and rotation mechanism is automated so much as it aim directly to its intended target swiftly. The vehicle is equipped to carry out limited battlefield repairs independently. In addition to being a threat to ground targets the tank's missiles could also engage aircraft.

The CSAT updated the tank and rearmed it :
- They changed the engine due to his danger for the crew. The mammoth explosion made radiation for decades in the area and killed the crew years later even if they leaved the tank.
- There is now 2 Gaz Turbines in the engine compartment,
- They also installed two 188 mm Cannons instead of the twin 120 mm.
- The turret armor is thicker than before.
- In order to modernize it's capabilities they installed a radar in the turret nose between the cannons.


-weight :150 tons.
-maxspeed :35kmh.
-armament : Twin Cannons 188mm AP,HE,X66 Machinegun and 12 missiles AA and AG.
-Armor can auto-regenerate until 50%.

To install X66-Mammoth Tank you should use modfolders to keep it seperate from the official game content to prevent issues.
With Arma 3 you can use different ways to set up your modfolders to use custom content you have downloaded.
Please visit the Arma 3 Mod install instructions page for more information about using custom mods and addons in Arma 3.

Known issues:
- Missiles fire effect stuck to the left missile pod. Spent lot of (hours & days) by testing changing,testing again.... to fix it. Not yet found how to do.

This mod is the result of my passion about video-games, I mixed the command and conquer famous unit into Arma,
This is the first addon i am publishing. I did my best to make this unreal unit fit well into arma game. I told myself "what if the tank would exist, how it would be in Arma..."

I'm currently fixing the reported error/bug on the tank.

Thank you for your FeedBack and bug report, working on it.
