Item #: SCP-XXXX

Object Class: Euclid

Special Containment Procedures: Foundation web analysis bot Simnea-3 is to monitor weather services globally for developments and predictions matching SCP-XXXX key signatures. Upon detection of a possible SCP-XXXX instance, MTF Beta-116, "Red Pioneers", is to be alerted and deployed.

Once the SCP-XXXX instance is located, MTF Beta-116 is to establish defensive positions countering the expected SCP-XXXX-A group. If deemed necessary, additional forces may be requested, with priority levels up to 14-Blue. For expected SCP-XXXX-A group compositions, see document XXXX-TL.

In case of a successful defense, SCP-XXXXs perimeter is to be secured until demanifestation and cover story Aroa-6 (military maneuver/exercise) is to be distributed.

In case of an unsuccessful defense, MTF Beta-116 is to regroup and hunt down all remaining SCP-XXXX-A instances. Tactics and equipment may be adjusted depending on expected versus actual group composition. Once all instances are terminated and SCP-XXXX has demanifested, cover stories and amnestics are to be deployed as judged necessary.

Description: SCP-XXXX is an interdimensional gateway, manifesting a half portion of a bridge. The position, style and apparent design age of these manifestations can vary from basic wooden constructions to 1920s era full-steel structures, set apart into 4 distinct types. For details, see document XXXX-TL. The manifestation of SCP-XXXX instances is always accompanied by certain weather patterns, including a thick, lasting fog.

SCP-XXXX instances are not active immediately after manifestation, but instead, gradually collapse their “cut-off” point into a dimensional fold. This process typically takes 70-80 hours but can be prolonged up to 300 hours by use of reality anchors.

Once active, the SCP-XXXX instance will produce a group of SCP-XXXX-A instances. SCP-XXXX-A instances appear human but are generally unwilling of communicating outside their group, discounting shouting and battlecries. An attempt to communicate by an SCP-XXXX-A instance has only occurred once, during Incident XXXX-23, and produced no actual exchange before the expiration of the subject. For details see Incident Report XXXX-23B.

SCP-XXXX-A instances always appear as soldiers or equivalent, carrying equipment matching the type of the SCP-XXXX “mother instance”. SCP-XXXX-A behavior, while differing slightly depending on their type, is always hostile towards the local population and defenders. If allowed to operate unhindered, SCP-XXXX-As pose a serious threat to the local population and must be terminated by all means.

Once all SCP-XXXX-A have been terminated or have retreated over SCP-XXXX, the XXXX instance, as well as all corpses and equipment left behind by SCP-XXXX-A, will demanifest by decomposing or corroding at extremely accelerated speeds, estimated to be around 15000 times faster than normal. Due to this extreme decay rate, no detailed analysis of SCP-XXXX-A instances and equipment could be conducted as of yet, but they appear to match their historical analogs.

The other side of the SCP-XXXX gateway, classified as SCP-XXXX-B could not be analyzed as of yet, due to the extremely hostile behavior of SCP-XXXX-A and SCP-XXXX quick demanifestation afterward.

As of yet, all instances of SCP-XXXX have occurred in rural areas with a population density of less than 10 people per square kilometer. The current consensus is that SCP-XXXX can not manifest in dense, urban areas. However, a standard procedure for that eventuality is to be developed immediately.
