General Parker did note his gratitude to the Forgotten providing the services of the man known only as 'Ghost Stalker' to perform dangerous missions for the GDI particularly in Tiberium danger zones where shiners are immune. GDI can't afford to lose such troops to the effects of Tiberium or Tiberium creatures.
Commando's take many years of rigorous training to produce viable troops for the kind of highly specialised missions Commando's go on. But for now, they are so expensive to produce and customised for the particular needs of the GDI Commando. It might take 20 years but eventually, we'll be able to mass-produce suits based on this technology for troops going into Tiberium danger zones. This is the most cutting edge technology that GDI has used to develop this suit lightyears ahead of mechs like the Wolverine and Titan. It augments the wearer's strength and speed but most importantly offers protection from Tiberium to the wearer. For those unfamiliar with the General, Havoc his codename from his fieldwork back in the First Tiberium War as a frontline commando. General Nick Parker was the biggest supporter of the Havoc Armor project so much so he put his stamp of approval on it dubbing it 'Havoc'.
