@Asalto: If you think the ROK Navy is impressive, just wait till I show you what the Royal Thai Navy started putting into service.
@Sakura_F: No, that would be too gamey. Im not going to coup or do anything like that to any country I am at war with, whether it is Australia or anyone else.
@Sumeragi: Im sure with a few tweaks and whatnot you could turn one of those things into a bit of a light Aircraft Carrier. Besides, its 2018, by now I am sure either Japan, Korea, or many of the other pro-Japanese states have designed some small VTOL strike fighters that could be used from the ships.
@CylonAndrew & Nathan Madien: Well, its been almost a decade since North and South Korea were reunified, so I think its fair to say that by now, Northern Korea would be going through a big economic boom. Lots of jobs in reconstruction, the ROK military, infrastructure, Japanese and Southern Korean financial investment, Northern Korea would probably be experiencing growth similar to what happened in South Korea during the 1960's and 1970's.
@everyone else: thanks for the comments!
Darwin: Northern Australia. Coalition reconnaissance units detect the approach of a large Japanese military invasion force approaching the city. Local Coalition forces now go to action stations as Japanese Marines knock on the gates of Darwin. The marines face heavy opposition, battling it out with local Australian army units, some Brazilian troops, and a brigade of Britain's elite Special Air Service (SAS) commandos.
The fighting is ferocious, and Japanese marines take heavy casualties in the streets of Darwin, especially at the hands of elite SAS soldiers. However, after a few days of combat, Coalition troops are forced to withdraw from the city. Darwin is secured, and Japan establishes its foothold in Australia.
Japanese marines are very quickly joined by the next wave of the invasion force: thousands of Japanese troops that had been waiting in East Timor and New Guinea. With reinforcements in place, Japanese troops begin to expand their bridgehead into the countryside around Darwin. Australian army forces fight hard to every inch of ground, but the advance goes steadily.
However, the Australian Army proves itself to be a very tough opponent. Australian troops gather south of Darwin and counterattack Japanese units around Katherine. Australian tanks drive into Japanese lines and force Japanese units to withdraw back to the north.
To keep up the momentum, Japanese forces attack to the east, along the coastline. Enemy resistance is very heavy, and the Australian army does not give up ground easily. However, Japanese firepower is able to drive the Australians further and further away from Darwin.
The Japanese advance soon runs out of steam however. Japanese troops run right into secondary lines of resistance, manned by heavy concentrations of Australian units. The Australian army is able to halt the Japanese advance right around Mount Isa, something that fills the Australian Army with a great wave of optimism.
Japanese troops then try to attack along the center of the front, hoping to achieve a breakthrough. Once again though, Australian resistance proves to be too hard to break, and this attack is called off.
Sensing weakness, Australian forces launch their biggest counterattack yet. Starting at Wave Hill in the west, Australian heavy mechanized infantry units pounce on exhausted Japanese forces in the area, throwing them into a retreat to the north.
Japanese forces attempt to regroup and form strong secondary defense lines, but the momentum of the Australian counterattack cannot be stopped this far away from Darwin. Japanese troops are forced to abandon their positions west of Darwin, to link up with well rested Japanese units further east.
Australia's Army has proven to be a much stronger foe than previously thought. All Japanese attempts to achieve a breakthrough along the northern front have foundered in the face of heavy enemy resistance. Worried that the Australian campaign could turn into a costly debacle, Japanese commanders move quickly to shuttle in fresh reinforcements, all the way from China.
After arriving at Darwin however, the reinforcements are ordered back on to their ships, sailing along the western Australian coastline to the major city of Perth. There, they storm the city, defeating its undermanned garrison and establishing a new beach head. Hopefully, this will help divert pressure form the northern fronts and enable Japanese troops in Australia to achieve some kind of breakthrough.
