[i] The two atomic explosion in Hiroshima and Nagasaki in 1945 may have destroyed nothing but their targets, but they also shook the whole planet. The new weapon, more powerful and innovative than anything else even today, presented a new era of warfare; an type of warfare much quicker, much more efficient, much more decisive. And even though much more lethal, much less bloody, for its poor victims either evaporate or die from radiation.
No superpower left the chance to obtain that avatar of destruction. U.S. created hundreds of that weapon, followed by the Soviet Union. At that point, the entire planet was on the verge of doomsday as calibrated intercontinental nuclear missiles and bombers threatened to make the Cold War hotter than any other in the history of humanity -which would be mostly eradicated with unparelled swiftness.
Even after that threat subsided, the general idea of a nuclear war remained. Germany, France, England and Iran also got a grasp of those destruction-in-a-box canisters, while the nations who already had them made them even more deadly. Until there came a time when nukes seemed to have forced the world into peace; the usage of them as deterrents made sure that for as long as a nation had the power to exterminate the nations that oppose, noone dares to oppose them in the first place -not even the ones that also had nukes, for using them would cause the exact same attack on them. The same properties made sure that no nation with nukes would dare to destroy them for they would be defenseless, while more and more nations tried to acquire them to find safety.
Finally, at 2025, all nations had an arsenal of nukes, making it an almost mandatory armament of any conflict. This was a period during which, quite interestingly, everyone finally relaxed: now, nukes, a symbol of unmeasurable destruction, has become so easy to use to destroy the world, noone dared to actually trigger such a chain reaction. Therefore, the greatest diplomat of all times was found out to be a bomb. The possibility of such an attack, which could easily eradicate humanity, was fittingly called Mutual Assured Destruction, or M.A.D., for not one single sane man would dare trigger it.
How oblivious they were to think one of them would not get into charge eventually.
And in 2051, after the death of Queen Kate the 3rd, her son, Arthur the 6th took her place. He seemed to increase the budgets in military technology and physics, which later he reduced again, this time enchancing the industrial infrastructure of Brtain. And then, in 2058, he declared war on Germany, France and Switzerland. Poland tried to get involved, and went with Britain for some reason. The rest of the NATO and the United Stated tried to neutrally stop the conflicts, while Russia allied with Britain, Poland and some other slavic countries, essentially recreating a Soviet Union of sorts.
Of course, from that point and after, everything got worse. Germany allied with the called European Federation (France and the others) followed by the USA. Switzerland sent air raids on Poland cities, while a B-2C filled with 120 high explosive bombs, heading towards London, was shot down.
However, the climax happened when an unidentified flying object was detected at suborbital travel, like it appeared out of thin air. It was detected that it originated from somewhere at the Pacific Ocean, and that it had an error on its trajectory, which targeted unknown target, and while they tried their fastest to prepare countermeasues, 60 seconds later, the CERN was annihilated under a huge fireball, followed by a tremendous shockwave. Half an hour later, 30-megaton retaliation had arrived on New Pyongyang, at North Korea, and the third World War had officialy began. [/i]
You are one of the soldiers participating in World War 3. Despite the usage of nuclear explosives, and common opinion on the conflicts of such a war, conventional forces are mostly used, while any nuke more powerful than 300 kilotons is scarcely used, though those are usually of the megaton range and should be intercepted at all costs.
You can be anything you want, as long as it is acceptable and not godmodding: soldier, captain, artillery batallion commander, warship commander, pilot, missile launch commander, whatever.
