I am a Warrior.

No, i am more then that, i am a Marine, i am an instrument of Freedom.

This is why i am currently standing in line with the rest of my Platoon, 30 well armed Americans ready for battle,another Marine Platoon stands behind us and so on. a stage has been erected for our departure, a band plays Semper Fidelis as we sweat in full battle gear, rifles slung at our sides.

As the band stops our gaze turns to the older man marching up the stage steps, the ageing warrior has seen battles since before we were born. Standing tall in the midday son he addresses us all.

"Marines,today will be a day long remembered in the History books of the world, the JSDF and the USMC will deploy together in the same AO and will work with one another to acompllish our goals, these people are our allies and as you all know their is no better friend and no worse enemy then a U.S Marine, Oorah"?

"OORAH"! we replied, our blood pumping.

"Well then, good luck Marines, let's show these sons of bitches what Leathernecks are made of" he shouted and with that, the large gate slide open to reveal something out of a history book, a large marble archway. We march in file as marines before us, onwards

Onwards through our Gate to the new world.

...

In 20XX a Mysterious Gate appeared in the middle of Tokyo's downtown shopping district Ginza, an Army marched out and and advanced into the city, leaving death and damage in their wake, through the actions of the Tokyo Metropolitan Police, an off duty SDF trooper and SDF themselves, the Army was beaten back, their weapons where that of the Roman Empire, Steel Broadswords and Bows and Arrows along with sights like Dragons and trolls of which we had never seen.

Once beaten back, the SDF's took control of the "Gate" and held fast, meanwhile Japan passed new bill's through it's senate allowing the SDF full power to cross over to the other side of the Gate, and find those Responsible and bring them to justice.

The United States, a major friend of Japan with so many troops stationed in and around japan found it self drawn into the conflict as well after the death of an Off duty Marine reservist and a dozen tourists in the attack in Ginza.

So it was decided that a small force of U.S Marines would enter the "Special Region" and set up their own operation, working with the JSDF bring down those who had murdered their countrymen.
