The M577 APC, or Armored Personnel Carrier is the perfect vehicle to take to battle against Aliens. This Lego MOC has all the features including Turret, RE700 Rotary Canon, and DSGR Smart Missiles. There is even room for a small Minifigure crew. Nothing can stop this APC, it is explosion and bullet proof, and can roll over all sorts of terrain. Just make sure not to spill acid around it. This vehicle is the creation of Rick Brickham, and is made up of about 750 pieces.
