Item #: SCP-XXXX
Object Class: Safe
Special Containment Procedures: SCP-XXXX Is to be kept in the motor-pool of Site-19. SCP-XXXX is to be ordered to drive into its designated spot by personnel holding a rank equivalent to Staff-Sargent(E6) or above.
Description: SCP-XXXX is an M1A1 Abrams Main battle tank that does not require crew. SCP-XXXX will follow the commands of anyone with the rank equivalent to Staff-Sargent or higher while the Vehicle and personnel in question both have the same flag or emblem. Orders given while below this rank or equivalent will not be obeyed. The flag or emblem currently used by SCP-XXXX can be seen on the rear of the turret face and is not to be disturbed or changed from Foundation designations unless authorized by Level 3 personnel. Any who do not share the emblem or flag of SCP-XXXX will be fired upon if they move closer than 50 meters within direct line of sight of SCP-XXXX.
SCP-XXXX is currently available for use by any mobile task-force upon approval from Level 3 personnel. Recommended deployment in areas already devoid of civilians and friendly forces, as SCP-XXXX will see them as hostile and engage them in active combat unless specifically ordered not to.
Standard checkups and repairs are to be carried out on SCP-XXXX as if it were a standard Vehicle of the type. If standard parts are unavailable when maintenance is required SCP-XXXX has been shown to run with irregular parts, but at a lower rate than its standard, even if the parts in question should not mesh with its engine. SCP-XXXX is unusually fuel efficient and requires maintenance at a significantly diminished rate to it's conventional counterparts.
Primary weapon is unchanged from the standard 120mm smooth bore canon that is standard on the vehicle. The ammunition stored inside does not need reloading between engagements. Shell type fired is unknown and has been shown to adapt to the target being fired at.

Testing Log for SCP-XXXX:
Name: Dr. [Redacted]
Date: July 6th, 20██
Total Materials: 1 Maybach HL230 engine.
-Engine of SCP-XXXX was replaced with a replica World War 2 Maybach engine and put through standard maneuverability testing. SCP-XXXX was able to function with the Maybach at a reduced speed, bringing the maneuverability down to that of a standard M1A1. SCP-XXXX was non-functional until engine was installed. Original engine was replaced with difficulty upon completion of testing. Maybach had to be cut out as the engine had fused with SCP-XXXX. Further testing requested.
Name: Dr. [Redacted]
Date: July 30th, 20██
Total Materials: 1 Leyland L60 Multifuel engine.
-Engine of SCP-XXXX was replaced with a Leyland L60 Multifuel engine, and put through standard maneuverability testing. SCP-XXXX was able to function at reduced capacity for duration of tests and work without a problem for entirety of testing. the Leyland L60 was expected to break down after 3 hours of testing and continued to function for remainder of testing. Original engine was replaced with difficulty upon completion of testing. Leyland L60 had to be cut out as the engine had Fused to the mounting of SCP-XXXX.
Name: Dr. [Redacted]
Date: August 4th, 20██
Total Materials: 4 Class D Personnel.
-Class D personnel were used to crew the tank during standard testing operations. Upon closing hatches and being ordered to go through the standard maneuverability test all responses from Class D Personnel stopped. The standard unusually high maneuverability was demonstrated. Upon lack of contact from Class D personnel the hatches on SCP-XXXX were forced open. Class D personnel were missing. Further examination found blood in the gas tank of SCP-XXXX matching three of the four Class D personnel. The DNA of the fourth was found inside the engine's oil supply and track lubrication.
All further Biological testing has been suspended.
Addendum:
During standard use a Lt.[Redacted] has been reported talking to SCP-XXXX. With her fighting alongside SCP-XXXX's efficiency has increased by a furthur [Redacted] percent. However Lt. [Redacted]'s mental state is deteriorating, and she has begun insisting on sleeping on top of the engine deck between missions, despite all weather and other conditions present during the night. Possible psionic testing to be administered.
Date: September 5th, 20██
Lt. [Redacted] Has been shown increasing insistence and aggression towards spending her nights atop the vehicle. To determine effects she was placed in containment to stop her from spending a night on the vehicle. Breakout attempted.
Casualties include: [Redacted], her two assigned guards and at least 5 D-Class personnel. She has shown remorse towards this act, but is still insisting on staying with SCP-XXXX.
Date: September 8th, 20██
Lt. [Redacted] Entered SCP-XXXX during the previous night. SCP-XXXX proceeded to travel to the testing range run though the testing track. Observers noted an unusually high scoring on target acquisition and movement, even above the already increased effectiveness of SCP-XXXX. Lt. [Redacted] (Now to be refereed to as SCP-XXXX-1) left the vehicle the next morning and is currently in containment for study.
