Palehorse Battalion

A group of U.S Marines survivors who accidentally wandered to the Otherside while training in the mountains of Okinawa. The unit was able to survive and set up a base in Kisaragi Station (which they also call Station February) for over a month before they met Sorawo Kamikoshi and Toriko Nishina.

Background
The Palehorse Battalion is a group of USJF Marines that were conducting a military exercise in the mountains of Okinawa. Not exactly knowing what triggered it, the group had accidentally wandered to the Otherside. They managed to gather their scattered company together and deployed their base within the station building but still, unfortunately, had taken a few casualties. Some of them went mad or disappeared. A number of their soldiers were also influenced by the bear traps (also called glitches), running off to the wilderness, even causing more casualties, and had to be taken down by their own comrades. They managed to survive for a month, before running into Sorawo and Toriko when they are being chased by the Walking Gallows.

The Marines, who were already at their limit, were immediately wary of the two new strangers suddenly appearing out of nowhere but Lieutenant Will Drake welcomed them to safety and introduced them to their commanding officer, Major Ray Barker. They explained how Kisaragi Station is surrounded by bear traps and how difficult it was for them to leave or escape, so they prioritized surviving for now. A train also passes by the station, filled with creatures they call the Monkey Shines which the soldiers fear and were reluctant to engage with.

After the Face Dogs that attacked the soldiers were defeated by Sorawo and Toriko, they continued their search for a way out, losing more people on the way, before the girls finally returned to rescue them. They chose to put their trust in Sorawo and Toriko, relying on their help to escape the Otherside and return to the surface world. Because Sorawo can see the glitches, she was able to guide them from the Kisaragi Station to the Palehorse Batallion's suspected entry point and eventually back to the surface world. In addition to allow guiding them past the glitches, Sorawo's eye also rendered the Otherside entities vulnerable to small arms fire, allowing the Marines to kill numerous Mossmen using their rifles, firing from within the armored "doghouse" attached to the roof of their armored MRAP vehicles. Thanks to Sorawo's help, the Marines managed to drive off a massed attack by Mossmen, and Toriko and the MRAP crew also eliminated the Kankandara using the robotic arm attached to the vehicle used for disabling IEDs. In spite of the massed attack by Otherside entities, thanks to Toriko's assistance, the Palehorse Battalion suffered no casualties in the advance from Kisaragi Station to the exit point. Upon reaching the exit, the surviving Marines of the battalion escaped to Otherside back to Okinawa.
