United System Research Base security guard
Security guards at the SERVEYOUinc-operated United System Research Base were under the command of August Hart.
They wore uniforms and helmets obscuring their faces and were armed to their teeth. (COMIC: Whodunnit?) Apart from following Hart's orders, they were in charge of enforcing station regulations, even such insignificant ones as the prohibition on running in the corridors. (COMIC: The Sound of Our Voices)
At least six security guards accompanied Hart in Hangar 18 to meet the intruders from the TARDIS. (COMIC: Whodunnit?)
One security guard was attacked by ARC and sent to a coma as the result.
Another security guard freed Hart from the interrogation room, where he was handcuffed to a table by the Eleventh Doctor.
Five guards led by Hart were waiting for Alice Obiefune and John Jones to return to TARDIS. (COMIC: The Sound of Our Voices)
