Remnant vs Earth

Description: All of Earth's militaries vs Remnant's Huntmen and Huntresses, Atlas Military, White Fang, Bandits and Grimm.

Main Character: Y/n L/n. A 20 year old Private First Class in the US Army. Him and eleven others are on patrol in the streets of Vale when he/you encounter Teams RWBY, JNPR and CFVY doing the same.

Year set in: The year it sets is 2040.

Was Remnant transferred?: Yes. All it's kingdoms, Continents and lands were transferred to Earth.

What about Earth?: This Earth still had Covid, but was completely removed within the Summer of 2021. Russo-Ukraine still happened in 2022, but this caused a Civil War in Russia that was won by the Anti-War/Putin Party. Also ending the war in Ukraine and getting peace talks with NATO. The Chinese government didn't like the peace with Russia and the West so it began starting a military build up and having troops near Taiwan, India, Mongolia and Russia. However, an anonymous hackers leaked it to the citizens and military personnel on the government is planning. So a coup happened which build up to another Chinese Civil War that ended by 2030 with Pro-Democracy winning against Pro-Communist. And so a domino effect happened across Asia and the Middle East resulting in countries going democracy left and right.

Note: Earth weaponry can go through Arua like a hot knife through butter. Since Earthlings don't have Dust, Arua or Semblance. Which also makes targeting anyone with a sniper rifle child's play unless there's a Faunus in the group.

Relations with the Faunus?: US, Japan, Russia, Republic of China, Australia and Canada treat Faunus as war refugees and gives them rights.

Geneva Convention or Suggestion?: Both the US Army and Marine Corps use Flamethrowers now. Russian Army uses Willy Pete. Middle Eastern troops hang Atlas soldiers. And most Huntmen avoid Chinese troops due to them specifically targeting Huntmen with a Semblance.

Characters?: Ruby likes seeing the weapons, but she's extremely terrified of the USMC.
Jaune wishes to try and make peace with some of the nations.
Coco loves Earth's fashion, but would think twice even setting foot on any nation's soil.
Weiss is scared beyond rational thought as she found out that both her and her family are now HVT due to a certain six countries wanting them Killed or Captured.
Yang is also terrified of the USMC due to both her and Ruby finding a video of them drinking cobra blood.
Blake and Velvet would rather surrender to either Canadian or American troops as she's a Faunus.
Pyrrha is scared of the A-10 or the BRRRT it makes.
Ren and Yatsuhashi also wishes to make with the nations.
Fox and Nora are terrified of the US Flametroopers.

Where did this idea come from?: From the top of my head.
