Jerkov (born February 29, 1972 in Siberia, USSR) is Claude's first contact in the Industrial Sector. He is a known criminal in both Anywhere City and in Russia. He was kicked out of the Russian army in 1989, and in 1994 was linked to a number of deaths in America's underworld. He disappeared shortly thereafter but was spotted in a knife attack in 1996. He was arrested and tried for possession of heroin, a drug he is addicted to, in 1997 but was acquitted when the evidence was lost. He is also suspected of disembowelling a rival gang member. He is married to Sandra Tito, a Serbian refugee, and they have a son. He is also known as Junkie, Soldier and Smiler.
Jerkov is a high ranking member of the Russian Mafia who are jealous of the USA's products, so they steal vehicles and weapons to sell back in Russia. The Russians are against The Zaibatsu Corporation and the Hare Krishna. Jerkov employs Claude to help the Russians gain full control of the Industrial Sector. Later in the storyline, Jerkov sends Russian assassins to kill Krishna leader, Sunbeam, but are thwarted by Claude. The Russians were wiped out, along with the Hare Krishna and The Zaibatsu Corporation, as Claude was not only working for the Russians, but also for Sunbeam and Uno Carb, leading to the weakening of all the gangs. Enraged, all three leaders attack Claude, but are murdered by him instead.
