Steel Tide + Nation-Building + World War + Technological Warfare
After transmigrating to a poor, insignificant country in another world, Su Wen becomes the newly appointed leader of a rebel army. The national military forces close in from every direction, while the empire's aircraft carriers loom menacingly offshore.
Armed with a weapons marketplace, Su Wen summons weapons, recruits troops, overthrows a corrupt regime, and establishes an independent nation.
When Abrams tanks form a steel tide, when long-range rocket artillery bombards across the sea, when sixth-generation fighters dominate the skies, when drones rule the battlefield, when hypersonic missiles strike across the globe, and when a million powered armor suits enter service...
The nations of the world are dumbfounded. How are they supposed to fight this war?
(Weapons progress from outdated to advanced; it doesn't happen overnight.)
(This is a fictional world, not Earth. Please don't compare it to reality.)
Beautiful, beautiful, beautiful, beautiful, so beautiful! ٩(๑^O^๑)۶
It's a fictional world, but it can easily be set against an Earth backdrop, which is great.
