Soviet engineers

Several ''' ngineers''' working for the Soviet Union in maintaining weapons and other technological equipment.

History
Shortly after the Cuban Missile Crisis, several engineers were sent to a Colombian peninsula to maintain the various weapons on the base.

During Operation Snake Eater, various engineers at Groznyj Grad were forced to work on the Shagohod without rest until it was completed. Volgin also deeply considered killing the engineers in order to keep them silent. These engineers were presumably killed when The Boss managed to destroy Groznyj Grad with the remaining Davy Crockett.

Post-Snake Eater
During Detente, the engineers were stranded on the San Hieronymo Peninsula after the Soviet government abandoned them on there when the development of their missile base was cancelled. They didn't suffer much negative consequences of this action, however, as they still did their job in maintaining weapons.

During the San Hieronymo Takeover, the various engineers were given an additional job by Gene and the FOX Unit of completing the stolen ICBMG prototype as well as Metal Gear RAXA at the assembly plant. In addition, at least one engineer revolted against FOX and ended up imprisoned in the Warhead Storage Facility's third basement. Several engineers were later recruited by Big Boss and his resistence. In addition, various engineers, shortly after the ICBMG was completed and delivered to the silo, ended up committing suicide due to despairing for their crimes and presumably due to Gene's influence.

Behind the scenes
If the player disguises himself as an engineer in Metal Gear Solid 3, the engineers will see through his disguise and will very quickly sound an alert.

In Portable Ops, the player can recruit various engineers.
