Third World War (Third Iteration)
Timeline manipulation by Anatoly Cherdenko also altered the circumstances surrounding the MCV. The widespread adoption of the MCV and construction yard concept occurred only prior to the Third, and not the Second, World War. These MCV's were much more advanced then their timeline erased predecessors in that they were heavily computerized and had amphibious capability.

Allied
Support for the adoption of the MCV Battle Command and Supply System followed favorable theoretical analysis.

By the, the front-line Allied MCV was an advanced automated design by Strauss-Fuhrmann Autowerks of Germany. It was amphibious and could readily repack from a back into an MCV.

Soviet
The Soviet MCV of the Third World War was designed by Arkhangelsk Tank Plant. It first caught international attention while providing relief to earthquake victims in Smedznegorsk, Ukraine. MCVs went on to provide disaster relief elsewhere and spur economic development in poor areas. The opening Soviet offensives of the war originated from forward bases and munitions constructed worldwide by MCVs diverted to military purposes.

Empire of the Rising Sun
The existence of the Imperial MCV was unknown to the Allies until it was fielded during the Battle of Green Island. The Allies correctly suspected Imperial espionage played a role in the design an investigations led to the imprisonment of Bart Truxton. Soviet investigation led to the arrest, and later death, of Maxim Novikov. The two men were later exonerated after the Allies broke the Wistful Blossom encryption and discovered the ingenuity of Imperial intelligence.

The Imperial MCV used in the Third World War was reportedly constructed by Gomusubi Heavy Industries. It was amphibious.
