Mobile war factory

Mobile
The Mobile War Factory was introduced after the Second Tiberium War to allow GDI commanders to produce units right where they needed them, close the the battle. The unit was about as heavy as a Mobile Construction Vehicle so it could only move very slow around the battlefield. Also it needed to be escorted as it was not armed. However, it did have heavy armor which could withstand a smaller attack.

Deployed
When deployed, the MWF was a fully functional war factory capable of producing all units available in the arsenal.
