The MT-101 Armoured Drilling Unit or ADU is a Mars Mission set containing a heavily armed and armoured Astronaut drilling vehicle and an Alien speeder. The MT-101 Armoured Drilling Unit is a mining vehicle unlike any other. It includes a capture pod where a sled capable of carrying an alien minifigure or three crystals is stowed. Another feature of the Armoured Drilling Unit is the dorsal sphere launcher near the drill. It "shoots" a blue sphere with the touch of a lever. The ADU contains 635 bricks, which is only 60 more than its sister set, the Crystal Reaper.

The mightiest Mars Mission vehicle of all!
Rumbling across the rocky surface of Mars, it's the MT-101 Armored Drilling Unit! With 2 detachable flyers to scout and protect the main unit, this special-edition mining tank is really 3 vehicles in 1. Includes a drilling arm to dig for energy crystals, a sphere-launching blaster, alien capture tubes, and 6 big wheels with working independent suspension for rough terrain! Plus an alien attack ship out to steal the crystals!]

"With independent suspension for its six wheels, a giant drill for mining crystals, a firing launcher and the ability to separate into the vehicles to fight an alien attack ship, the special-edition MT-101 was one of the most popular Mars Mission sets."
