President Biden made a public address to North America through CNN.
"Good evening, people of the United States of America, and people of Canada. We, the United States of America, engaged in a skirmish with an unknown mechanized group known as the Kaiser PMC that invaded our borders some time ago. The result of the engagement was a great victory for our side, and our government discovered that the place we were transferred to was an Academy City called Kivotos. We, the United States of America, will no longer allow them to be dominated by the tyranny of the Kivotos, and we declare war on the Kivotos Academy City and the ten academies that make up its federation!"
The audience applauded as Biden spoke. As if hinting at the future, Biden smiled broadly.
[14 hours after the declaration of war, Gehenna Academy]
"pop! Puffup!"
An M1A2 SEP v2 belonging to the United States Army fired a shell at a Tiger 6 Tank belonging to Gehenna Academy. The Tiger was immediately destroyed and another Tiger nearby fired a shell at the M1A2, but the M1A2 is a 3.5 generation tank that is considered the best among modern MBTs, and the Tiger was a tank during World War II that could not fit into the MBT. The M1A2 immediately blocked a shell with its front and fired a shell at the Tiger. The US-Gehenna Academy tank battle ended so easily.
[Above Kivotos Central District, Sanctum Tower]
One squadron of F-22s from the US Air Force, F-35As from the Canadian Air Force, and one F-15E from the US Air Force bombed the Sanctum Tower and carried out an operation to confuse the enemy camp. It was a very easy operation to indiscriminately bomb the Sanctum Tower with air-to-surface missiles while one F-35A and F-15E hybrid squadron shot down enemy anti-aircraft helicopters.
As per the operation, a combined F-35A and F-15E squadron shot down the Apache helicopters of the Valkyrie Police Academy with AIM-120 air-to-air missiles. Colonel Smith, commander of the F-35A squadron of the Canadian Air Force, said this after seeing the downed Apache helicopters at the Valkyrie Police Academy.
"The tanks here are at the level of World War II in our world, but making Apache helicopters, well, not as good as the Apaches in our world."
Regardless of what Colonel Smith muttered, a squadron of F-22s from the US Air Force fired dozens of GBU-57 air-to-surface missiles at the Sanctum Tower for its assigned mission. The Sanctum Tower collapsed powerlessly with GBU-57's penetration.
[Red Winter Federal Academy Area]
"pop"
A T-54B belonging to the Red Winter Federal Academy fired a shell at the M1A2. they immediately defended it from the front, but the vibration was a little strong.
"Kuh! They use the T-54 because they are commies!"
However, it could not be the opponent of M1A2. The M1A2 immediately fired back fire. In the end, the T-54B was destroyed.
[72 hours after the declaration of war, a Gerald R. Ford-class aircraft carrier]
After 72 hours of declaring war, Kivotos finally surrendered. The President of the Student Council of Kivotos signed the surrender document on board the Gerald-class ship. By the signing of the president of the student body, the US-Kivotos war ended like that.
