First Tiberium War
The United States of America and England together made an offensive into Tanzania using GDI's land, sea and air forces to overlook what the Brotherhood is lurking in Zaire, but didn't see much of the Nod forces in Kenya and around Tanzania. The GDI forces created a new Mammoth tank that can defeat the Nod forces and help the Tanzanian President with this on Zaire as artillery batteries at the western rift. Kane sent the Nod Commander to destroy the facilities which included the research and it was achieved before Nod forces forced the Tanzanian government to surrender and killed both GDI Commanders in charge of Mzuzu and the Tanzanian armed forces. This happened in a late middle and nearly close to the end of the First Tiberium War.
