While the Mammoth Tank has been an iconic part of GDI military for many years, they are slowly being replaced by more technologically advanced mech and hover units, such as the Titan and Hover MLRS. While these massive brutes stand up to a fight against more modern GDI vehicles, their high price tag and maintenance costs have put them out of favor in the recent decade. Some GDI commanders also view them simply as too slow for the modern battlefields. Despite the modernization efforts of the GDI military, some old school commanders have been against the decision to completely replace the Mammoth Tanks. To keep both sides happy, high ranking GDI commanders are still given the option to put them into action on critical missions. However, since they haven't been in production for years, only 5 of them can be ordered during a single battle. Once this number has been reached, they are no longer available to purchase, even if all the existing ones get destroyed.
