The UN Ground Forces (UNGF) is the land-based service branch of the UN Armed Forces (UNAM). Its regular forces consist of 5.5 million personnel, with an additional 9 million personnel in reserve (mobilized during the Ki'sa Wars), making it the largest active standing army in the human known space. The UNGF furthermore deploys 189,000 Heavy Exoskeleton units and 8.5 million VI drones. Currently 90% of the ground force divisions and brigades are either armoured or mechanized to deal with potential threats. The UN Ground Forces has and continues to undergo rapid major upgrades and re-structuring to deal with future land warfare, with front line troops, special forces, and marines given priority in receiving newer modern weapon systems.
