The Commissioned Officers Challenge, also known as the COC, was a challenge set aside by the rogue UER Commander to see the UEF Forces' powers and strength. As that was happened, the rogue UER Commander caused too much bombings, which disturbed the UEF Armed Forces and its allies' focus against the UER Forces. This would caused the Expeditionary Admiral to postpone this fight and challenges the UER Ultranationalists, however. The best UER commanders was Twilight Sparkle, Rarity, Applejack, Fluttershy, Rainbow Dash, Octavia, and The Great and Powerful Trixie. The Coalition Forces chose Expeditionary Admiral Grant Gerard DuGalle Calliope, Assault and Lasers General Heinrich Rudolph Absel, Air Force and Helicopter General Marshal Peter Patton, Commander Harkovich, Stealth General Shaso Ka-is, and Starbeam Twinkle. The officers of the United Earth Federation Armed Forces had their forces poorly trained, but they are better trained like Zero Hour Reborn: The Last Stand.
Before the battle, both forces have equal numbers. The bases has equal numbers but the entire defences were put in every places to protect their bases. The UEF sends every infantries especially Juggernauts and Riot Shield squads. The two factions battles with armored tanks. However, the Expeditionary Admiral was still absent from the challenge and was still continuing his attack on the UER headquarters. This was a distraction that the Admiral ordered all to focus their attacks on the UER base while his forces will drive the "fascist-krauts" out of his occupied zones' soil. He will begin to distract the UER forces with MW3 Weaponries. He also sends the entire UEF military forces to his comrades while he has to use the DSS Aleksander. The Starbeam Wing engages the entire aerial forces while Storm Wing engages the UER forces on the ground. The battle on the Challenge area has been crippled, but the Admiral sends in his only armored tanks - the Mammoth Tanks, which was never used by any UEF or UER Loyalists, and his Hover Crusader Tanks - which isn't also used by any UEF and UER Loyalists officers. The Admiral of the Expeditionary Forces used those tanks to win, and he sends his armored forces. While he has multiple forces, the joint UER-UEF forces then destroys the UER Command Centers which was scattered all over the areas. The UEF Expeditionary Military was still in combat, but the NLR informs the Coalition Base that the UER Ultranationalists then has the Ion Cannon and their command center. The NLR Command also says that the only way to end this conflict is to put an end to the Ion Cannon and the Command Center. The NLR and the Solar Empire Command said that the rogue UER commander was Autumn Winters - a mare who convinced every UER personnel especially the Generals, but Starbeam Twinkle and the rest of the UER Forces who were still loyalists who supported the UEF Armed Forces. The entire UEF Armed Forces crippled the UER Ultranationalist Armed Forces' Command Center and the Ion Cannon, which caused the UER Ultranationalists to surrender. The Third Reich informs them that Autumn Winters is about to escape, but was being stopped by Andrey's Valkyrie missile launcher. The joint NLR-Solar Empire Forces captured Autumn Winters for convincing every UER forces to destroy the United Earth Federation Armed Forces. Autumn Winters says he will destroy all human forces which they allied the UER. But the entire officers of the United Equuestrian Republic and the United Earth Federation begins to move forward, but the Admiral Grant appears in his Marine Raiders Rescue uniform with his Scoped Springfield Sniper Rifle with a bayonet. Commander Sherman then walks forward, Autumn Winters is calling the Admiral a fool but he knows that the Commander aims his sniper rifle at him. He executes him, only to free the remaining UER personnel from Autumn Winters' control.
