American technician (Ngumba Industrial Zone)

An American technician as well as his female assistant were dispatched to the Ngumba Industrial Zone by Skull Face and XOF to observe the test subjects of the vocal cord parasites. However, they later requested to be rescued shortly after the facility was burned to the ground after they were held hostage by Cipher. The Diamond Dogs via Venom Snake proceeded to rescue them. After being brought back to Mother Base, the duo revealed all they knew about what was going on there, including that the tapes Skull Face was recording inside the throats of some of the specimens was in another language, and that no English copy existed.
