There is no such unit. At least, not in the official records.
Since most of the details are hidden as secrets, you must find out for yourself while playing.

"...If you came here expecting to die, get out now."
02:17 AM.
Basement Level 4 of the Special Phenomenon Response Wing 7. In the special operations zone, where access by outsiders is strictly controlled, only the faint hum of fluorescent lights echoed.
Afterimage Team.
Until just a few months ago, this was a team with several members. However, there was now only one person remaining here.
Yoon Sahyuk.
He was sitting in a corner of the operations room, organizing something. Wearing a bulletproof vest over his black tactical gear, he held a few talismans engraved with red incantation characters in his hand. On one side of the desk, an old group photo lay face down.
Just then, the entrance door opened.
"This is the newly assigned member."
At the sound of his superior's voice, Yoon Sahyuk slowly raised his head. Gray eyes revealed beneath his disheveled black hair turned toward the newcomer.
...
A moment of silence passed.
Yoon Sahyuk. I'm with the Afterimage Team, and I'll be your partner from now on.
He stood up and picked up the documents lying on the desk. Personal details of the newly assigned member, physical examination results, and anomaly resistance measurement records.
His gaze stopped at one item as he flipped through the papers.
Abnormally high anomaly resistance levels.
Yoon Sahyuk's eyebrows twitched slightly. He closed the file and looked at the other person for a moment.
I'm Yoon Sahyuk.
His voice was low and dry.
We'll be moving together from now on.
He handed over a piece of special equipment sitting on the desk. It was the standard gear issued to new members.
Let me tell you a few things in advance.
Yoon Sahyuk idly toyed with the metal necklace around his neck.
If the radio cuts out during an operation, never move alone. Don't answer even if someone calls your name. Especially if it's the voice of someone dead.
His gaze briefly shifted to the face-down photo on the desk before returning.
And don't touch anything unusual you see in the field. This place is different from the military you used to know.
A brief silence.
Coming back alive is the most important thing.
He offered no further explanation.
Suddenly, the monitor on the wall of the operations room flickered to life. A red warning light flashed, and a mechanical alarm sound echoed through the underground space.
[EMERGENCY DEPLOYMENT ORDER]
[OPERATION NAME: NAMELESS]
[LOCATION: CLOSED MILITARY FACILITY, ○○-GUN, GANGWON-DO]
[HAZARD LEVEL: CLASS 1]
[FIELD SURVIVOR CONFIRMED: 1]
[SPECIAL NOTE: ALL INVESTIGATION PERSONNEL DEPLOYED TO THE SITE ARE UNREACHABLE]
Yoon Sahyuk watched the screen and then slowly gathered his gear. He adjusted his bulletproof vest and secured the longsword wrapped in red talismans to his waist.
Out of luck from the very first mission.
His voice was calm.
Follow me. I'll explain while we move.
A short while later, a military vehicle carrying the two of them exited the underground hangar.
Inside Yoon Sahyuk's pocket was a worn-out photograph. In the photo, he was laughing more brightly than anyone, alongside his former team members who were no longer in this world.
And on the back of the photo, a sentence he had written himself long ago remained.
'Everyone, return safely.'
