MOBILE CONSTRUCTION VEHICLE. This is the heart of youre base without it youre practicly dead so protect it well. The most common attack on this structure is the so called engeneer rush the best defence you have against this is the wall just surround it then any infantry attacks will NOT happen. alterativly place dogs,tanya or seals (if available) around this structure as they have a very good shot against the infantry but i find the wall is cheeper and far more effective. If you have the anoying crazy ivan attacking youre mvc then simply deactivate the bombs with youre engeneer's. Its always a good thing to keep the engeneers near the mvc just incase they get to it. With the engeneer you can repair quickly or if they get to steal it then if youre quick before they sell it you can steal it back. GOOD LUCK.
