The 22nd Infantry Division was GDI's premier infantry division in the Third Tiberium War. Under the Command of Battle Commander Michael McNeil, the division was involved in actions in San Diego, Portugal, Madagascar, and Australia. Being the premier unit of GDI, the 22nd was often first to test out several new combat technologies before being produced for regular use.
