Invasion of Ursus

Operation Freedom Bear, also known as the Invasion of Ursus, was a 2015 armed campaign waged by the Triumvirate, Galactic Alliance Defense Initiative and United Nations of Earth after discovering the Empire of Ursus's crimes against humanity, especially for its recent raids into Russian territory after the Terranians' arrival on Earth-ANIME three days prior to the start of the three-month One Sith War and its Earth-related spillover, the Godom War.
The invasion was preceded by Allied special operations forces infiltrating Ursus to sabotage it from within to allow the invasion to proceed smoothly as well as rescue the laborers from Ursusian mining camps. After Ursus was crippled logistically, economically, militarily and politically, the Triumvirate, GADI and UNE invasion forces took the Ursusians by surprise through a sustained air campaign and the arrival of airmobile forces sent to quickly take over each nomadic city. Despite the Ursusian nobility's claims they are stronger and that the Empire of Ursus is invincible, the technologically-advanced coalition was later proven to be the much stronger force. The war ended when Emperor Fyodor ordered the shattered Ursusian military to surrender after special forces and combat troops arrived at the Imperial Palace. The Ursusian Instrument of Surrender was ultimately signed by the Ursusian government, putting an end to the imperial state once and for all.
The invasion of Ursus had took the Terranians by surprise, but it is the Ursusian Instrument of Surrender whose signing caused the dismantlement of the empire that shocked them even more. To date, the Terranians had thought that Ursus was the most strongest nation in their world, which had been proven wrong when the One Sith attacked; the One Sith forces' invasion of Terra was only halted by the arrival of Novayan rapid-response expeditionary forces under Lord Admiral Borealis I's command, allowing the Terranians to flee to Earth-ANIME. At that time, it was ultimately thought among Terranian circles that Earth-ANIME is technologically poor despite the fact it is also modern and had interplanetary colonies, and that the voidwalkers and their allies were too exhausted to fight, thereby allowing the Ursusians to continue with their imperialistic actions. Only when the coalition invaded and shattered the empire did the Terranians realize that they are not yet tired.
As a result of the invasion, partition and occupation of Ursus, several Terranian nations sought to align themselves with other factions on Earth-ANIME: the Victorian Empire, Laterano, Kazimierz and the Empire of Yan (also known as Great Yan) sought membership within the European Union and Shanghai Cooperation Organization, while Rim Billiton (located in Australia) began negotiations with the Australian government to annex it into its territory, [AWAITING DECLASSIFICATION].
