Being one of the few nations on earth to truly benefit from the European Great Wars, through the an extensive system of loans, the selling of arms and only minimal involvement, the United States was able to enrich itself while the great powers of old burned out. Although that didn't make them too many friends, it did allow them to establish their own 'stabilizing' military presence with bases around the world and the creation of puppet states in second world locales to secure vital resources.

Despite their lack of global war scale engagements, the US Army is one of the most powerful and well funded militaries in the world. Primarily a versatile, conventional force retrofitted with hi-tech developments like laser and anti-materiel guns, they also employ tried and true methods of human destruction like the use of napalm and 'overwhelming firepower' doctrines. On top of that their vast wealth and global connections allows them to hire mercenaries on the fly: self-armed and often local privateers who fight for the highest bidder - the US.

Founded amidst the rubble of the Second Great War, the European Federation exists to unify the most developed nations of Europe - politically, economically, and militarily - to counterbalance ever battling world powers, while avoiding strategic dependence on the US. Perhaps somewhat learning from the last two empire-driven wars, Europe developed towards a more democratic, representative state, and thus carefully picked nations who applied to join their union - rejecting those who's values and present conditions failed to represent the ideals of the Federation.

Still, that war casts a long shadow even decades later, as Europe's leadership is more concerned with ensuring their supremacy in the event that another war breaks out. The world's best scientists continue to develop exotic and highly secret weapons to ensure the Federation survives, bending the laws of physics to make it so, using advanced chrono-teleportation techniques to protect the expansive borders of Europe. So far, most of these devices have only been used in confidential training exercises, meaning that reliable eyewitness accounts of their effects are sparse...

The British Isles didn't suffer in the Second Great War as much as the continent and the kingdom maintained its position as a colonial empire. It wasn't, obviously, an easy job though. Watching as the people under French, Italian and Dutch rule broke free, the Queen's servants from India and Africa demanded their independence aswell. The day when Her Majesty's forces opened fire on protestors shifted the world's relations with Britain forever. It kept its colonies, paying in blood, but lost all support from the newly formed European Federation and the neighbouring continent at large.

Nevertheless, the Commonwealth Army maintained its position with the enormous effort of royal scientists, officers and workers. Their new doctrine relies on crippling the enemy's advance and visiting his backyard, thanks to advanced EMP technology and elite special forces. With deadly toys of their own, the United Kingdom is a great threat to any rebellious forces or pitiful second world countries who dares to question Britannia's rule.

While the Pacific War with the Americans ended in stagnation and eventual armistice, Japan's campaign of conquest in China came to fruition as the abundant natural resources, industrial centres and key ports fell under her control. Trade with other colonial nations in the region was allowed to flourish, making Japan the key to the orient and all the riches that awaited there, firmly establishing them as the world power they had always sought to be. Furthermore their mutual hatred of the communist threat made them perfect for an international axis against the spread of such dangerous ideas.

An unending dedication to the supremacy of their god Emperor led Japan to make many astounding developments in the coming decades of peace. They were the first to create weather manipulation devices, suitable for a nation with vast territories to protect and govern, spanning mountains and oceans alike. Further to that end, they employ multiple amphibious techniques to dominate the waves, cryogenic weaponry to bog down their enemies and advanced jump suits to control the skies, allowing the Empire's servants to outmaneuver any opponent.
