Defend Equestria from Lunar Invasion Forces

The people of Equestria are being invaded by the Rebel forces of Princess Luna, Heir to the Throne of Equestria. With the use of Chemical, and Biological Weaponry, Princess Luna has set discord loose among the people of Canterlot and Equestria. There are loyalist troops aiding Princess Celestia is the defence of Canterlot, but it very underhanded. Her Royal Guard, the Elements of Harmony are doing everything they can to protect the villagers of Equestria from discord and Princess Luna, but supplies are running thin with loss of several outlying colonies. We need the defence of the US Army Rangers to help the Loyalists from being over run by the Rebel Forces of Princess Luna
