Item #: SCP-XXXX
Object Class: Safe
Special Containment Procedures: SCP-XXXX is to be held in a small Level-1 Containment cell, it is currently located in Site-102 in ██████, Germany. All personnel assigned to SCP-XXXX must not be born or descended from the United States of America. One armed guard must be posted outside at all times and the security door must be outfitted with a C/A DNA scanner to ensure that any personnel attempting to enter SCP-XXXX's containment cell is not doing so due to its anomalous effects. Two other security members should be on-call within the Site in case of affected individuals attempting to force entry, neutralisation of the affected individuals is only to be used in extreme situations (as specified in Security Manual 0043). All personnel who attempt to enter as a result of SCP-XXXX's effects should be detained and undergo a psychological review until the anomalous effects wear off.
Description: SCP-XXXX is a poster that was commonly seen in the USA during World War 1 depicting Uncle Sam that states 'I WANT YOU FOR U.S. ARMY NEAREST RECRUITMENT CENTRE' - then it will state the nearest American recruitment office from its current location. How it knows where the recruitment office is or how it changes itself to state the office's location is unknown.
SCP-XXXX was first discovered after a series of disappearances were linked to the Imperial War Museum in London, England. Foundation personnel embedded within the local Police Force witnessed a man be pulled into it on 21st July 20██, it was then taken to Site-102 for research.
When any person who was born in the USA or who has had ancestry who lived in the USA between 1917-18 comes within a yet to be certified distance to SCP-XXXX (incidents have so far ranged up to 2,239 miles), said individuals will come under its anomalous effects:
1. An uncommonly strong sense of 'Americanism' and patriotism towards the USA.
2. An overwhelming desire to go to and salute the poster, how they know where SCP-XXXX is is another property undergoing research.
3. A hatred towards all German born people or those with ancestors who lived in Germany between 1917-18.
These anomalous effects have shown to wear off after a period of 3 weeks to 2 months.
Note that these anomalous effects do not occur to persons that themselves were not born in the USA nor had ancestry living there between 1917-18.
These effects will happen regardless of the individual's current status, attitude towards the USA, pacifist/religious views against war, or knowledge of what SCP-XXXX is or the event of World War 1 itself. Affected individuals will then go to SCP-XXXX by any means possible and salute it. Once they have done so, the illustration of Uncle Sam will reach out his right arm from the poster to take the individuals hand as would be normal for a handshake, then pull the individual into the poster. After which, the individual immediately disappears and the poster returns to its usual state.
After being taken through, testing using audio recording devices on D-Class test subjects has shown that the individual will find themselves as an American soldier on the western frontline in France or Belgium during World War 1 in the summer of 1918 (when American troops arrived in Europe), no other anomalous properties are apparent. Subjects have shown to show no surprise or alteration to their surroundings, and somehow have gone through the training received by American soldiers and are fully equipped as any other soldier of their particular regiment would be. Other soldiers that subjects have come into contact with do prove to be real people from the era who did fight during World War 1. Subjects will then go through the events of World War 1 as they happened, should they survive, upon reaching the 11th November, 1918; subjects will somehow immediately appear back in front of SCP-XXXX with no recollection of their participation in the war. Whether SCP-XXXX is some form of time-travel device, a hyper-realistic simulation, or a type of alternate dimension is currently unknown.
Interviewed: Test Subject-01, D-3410
Interviewer: Dr. ████████
Foreword: The following is an interview audio log between Test Subject-01 (D-Class 3410) and Dr. ████████ before all of the anomalous properties of SCP-XXXX had been discovered. After the anomalous effects had taken hold, D-3410 is handcuffed to a table and shows visible signs of distress. Note that Dr. ████████ is of German descent but currently is a Swedish citizen.
<Begin Log, 13.47pm>
Dr. ████████: Hello, D-3410. How are you feeling?
D-3410: Feeling like it's 'bout time to beat your German ass.
Dr. ████████: I'm not German, I'm from ████████████ in Sweden.D-3410: Yeah, yeah, sure. I've heard it all before, is there anything you fuckin' Jerries won't say to get out of a fair fight? [Note: D-3410 has had no previous contact with German personnel whilst under the effects of SCP-XXXX]
Dr. ████████: Okay… So do you have any other feelings or urges as of this moment in time?D-3410: Get outta here and get to Uncle Sam, I gotta do my part.
Dr. ████████: What is your 'part'?D-3410: Fightin' you fuckin' Jerries for America, of course.
Dr. ████████: It says in your file that you're a pacifist, you served in the peace corps for 3 years, why now do you want to fight?D-3410: Hold the fuck up, are you callin' me some kinda queer? I swear to god I'll beat your ass back to Berlin you piece of shit.
Dr. ████████: So what happens when you get to Uncle Sam?D-3410: I get enlisted, get my rifle, get my training, get shipped off.
Dr. ████████: Then what?D-3410: What d'you think, kraut? I get out there 'n' shoot you bunch of fucki-
Dr. ████████: -Yeah I get the message, so can you tell me how you would get to SCP-XXXX?D-3410: (Notable irritation at being cut off, repetitively clenching his fist) Down the hall, first right, past SCP-████, second left, down the stairs. Oh, and then I have to put my foot up your goddam ass.
Dr. ████████: (audible sigh) How do you know where to go considering that you have never been assigned anywhere near SCP-XXXX's containment cell?D-3410: Dunno.
Dr. ████████: Great, well would you like to go see Uncle Sam now?D-3410: As long as it aint no shitty trick.
Dr. ████████: I assure you it isn't.<End Log, 14.03pm>
Closing Statement: Following the interview, D-3410 was released. Immediately, he attempted to assault Dr. ████████ before he was sedated by security personnel. Audio recording chips were fitted into D-3410 and he was awoken. D-3410 then went to SCP-XXXX's containment cell and saluted. The audio recordings suggest that he was killed during the Second Battle of the Somme on 29th August, 1918 by [DATA EXPUNGED], an experimental nerve agent developed by Germany in World War 1 that is currently used by the Chaos Insurgency.
Addendum: Announcement from Dr. ████████: "DNA and family history checks must be taken on all Foundation personnel assigned to the east wing of Site-102 following the disappearances of 8 personnel, who were later found by surveillance footage to have been taken into SCP-XXXX."
