Izaak Sirkov was born on April 25th 1983 in Miroslavl, Chernarus. His father Antonov Sirkov, being a naval officer, desired for Izaak follow in his footsteps and took steps to ensure this. He had a military upbringing and had his life planned out from him from the start. He succeeded both in primary school as well as the academy and was well on his way to meeting his father's expectations. By the time 2009 rolled around Izaak was a member of the Chernarussian Navy and served under his father. When the crisis broke out Izaak was determined to take down the Chedaki swiftly and quickly. He was not prepared for what would come next however. His father was killed in action early into the civil war and this dealt a massive blow to Izaak. This was the man he looked up to all his life and hoped to one day succeed. Now he was dead and Izaak had lost all desire to serve in the navy. Fortunately thanks to his father's connections and reputations Izaak took interest into the COBR. He quickly impressed his superiors and became an operative. He was ruthless in his hunt for and purging of Chedaki and their sympathizers. He took pleasure in the brutal executions of its members during and after the war.
He continued to serve after the civil war eventually becoming the chief of the COBR. As time went on, he acquired a reputation for his brutal but efficient tactics for taking down local terrorists and Chedaki remnants. Izaak began to form a relationship with the President of Chernarus and became one of his most trusted operatives. He began to see the President as a new father figure and it only strengthened his loyalty to him. At this point, Izaak's loyalty lay with the President over the country and its people. When the infection broke out, Izaak did his duties as the chief as well as ensuring the President's safety at all costs. He was beginning to grow more and more annoyed and even enraged at how the CDF officials handled the disaster, especially the fall of his home Miroslavl. If it weren't for the President, his opinions of the current leadership could have turned into thoughts of mutiny.
Two weeks after the outbreak had arrived, the CDF was a shell of its former self. Only two battalions remained and they kept hidden in Staroye having lost much ground. The COBR unit was reduced to six men including Izaak. Now that the local police had perished, Izaak and his men volunteered to be the military police. They patrolled through the northern cities, seeing the civilian's struggles and the aggression from the VDV. COBR tried to ease tensions but they were horribly understaffed and needed assistance from the soldiers down south. Their requests were ignored and received no communication at all from the rest of the forces down south. Assuming they had been abandoned, Izaak and his men formulated a plan for their future endeavors. They would become a rogue unit who would recruit new members into their ranks, reclaim territory to the infected and make a name for themselves in hopes of getting the CDF leadership's full attention. Izaak, had become a Warlord of his group known as the Reclaimers.
