SCP-XXXX with SCP-XXXX -1
Item #: SCP-XXXX The Weapon of War
Object Class: Safe
Special Containment Procedures:
SCP will only displays functionality and anomalous properties when in possession of Sergeant Russo. Currently Sergeant Russo is attached to MTF ██████. The MTF is instructed that should Sergeant Russo become incapacitated or perish on assignment, the MTF will make all reasonable attempts to recover SCP -XXXX. Should Sargent Russo become possessed or have his capabilities compromised, MTF forces are to subdue the Sargent if possible. If not, lethal force is authorized and the SCP is to be recovered. Upon recovery of SCP-XXXX, the MTF will place it into a secure section of the Foundation Armory until the first born son of Sergeant Russo, ██████, turns 18. At ██████’s 18th birthday, SCP-XXXX will be given over and observed for active changes in SCP-XXXX. The child is to begin training but not be given a field assignment until they have a son born. This cycle is to be repeated.
Description: SCP -XXXX appears to be a Standard M4 identical to those issued to Foundation personal with 2 noticeable differences. The first is that instead of a standard magazine there is a double magazine. The magazine is designated SCP-XXXX-1 The second is that on the outside of the stock is the word "Aeneas." When any member of the foundation or any class D personal handle SCP -XXXX, it acts exactly like any other M4, limited only by the users abilities. The magazines act as standard magazines with 30 round capacity.
When SCP - XXXX is in the possession of Sergeant Russo, anomalous features begin to present. The first, the gun become inherently more accurate. Comparing the accuracy of Sergeant Russo while using the SCP vs. a standard issue M4 shows that his accuracy increases by 80%. The next anomalous property is that when one magazine is depleted and Sergeant Russo switches to the second magazine, the first begins to replenish rounds at a rate of 30Rounds/Minute. These rounds are identical to standard issues ammunition that is being outfitted to MTF ██████
The Foundation first learned about SCP-XXXX through Sergeant Russo himself, after he was recruited by the Foundation from the US Rangers. After he learned of the artifacts that the foundation oversaw and protected, he came forward and explained the weapon he called Aeneas which would later be given the designation SCP - XXXX. He surrendered the weapon for the first time for inspection and testing. Thorough tests were conducted by researchers, security personal and class D's against stationary targets, live animals, and Class D targets. Each test yielded the same results. SPC-XXXX acted as a standard issued M4. Sergeant Russo was then instructed to repeat the tests. This is when the performance abilities from above was discovered. SCP-XXXX will also change form to whatever the current standard issue service weapon is for the owner of the SCP. In this case, the M4 matching MTF███████.
SCP - XXXX is believed to be a gift from the goddess Aphrodite to the Hero Aeneas himself. This weapon is passed down from Father to Son in unbroken secession over the years.
Foundation Interviewed Sergeant Russo in the addendum for more information bout this discovery.
The Brother of Sargent Russo, ██████ Russo is currently living in ██████, ██████, USA, has been located and is being monitored. Should Sergeant Russo and his heir be comprised, the SCP should be given to ██████ Russo and training should commence for field assignment.
