There was an invasion of protogens on planet earth and they tried to take over the planet, but they were prevented by humans, some tanks and destroyers created by humans were able to destroy several armies of protogens and received improvements to technology, the war with protogens has just begun (war started 19-20 days ago)

Protogens are a more advanced race than humans, protogens have already managed to build huge bases for improving protogens and other equipment, they are more powerful than the human race.

They already have 1 Protogen titan - it measures 56 meters and has blue cyber wings, its fur is blue and it has a green face on its visor, and it has gold armor, and it has laser cannons on its arms, and it has an ultra jetpack on its back.

The humans knew of this invasion and were not caught off guard, they already had a large army, but they also had an advantage from the beginning since the protogens could not withstand the Earth's environment.

They also had tanks that were very powerful and had a lot of fire power, they also had a lot of vehicles, helicopters, boats, and other machines.

It still wouldn't be enough to destroy the protogens because they had already established bases around the world.
