Raised in the trushchoby of Moscow, Ilya didn't have always something to eat at the end of the day, while his older brother and sisters always had. His mother was an uncaring hag to him and his father was a military man fighting in foreign wars, the young boy was lucky to see him once a year. Even if his father wasn't a great role model, he was the parent he always looked up too. His brother and sisters on the other hand hated their father's and loved his mother, which only made the gap between the siblings deeper. Most of them turned to a life of crime, mocking the system they were born in and turning their backs on the loving father that brought most of the money home.
Ilya on the other hand, had another plan in mind.
Every time his father came home, he would ask him about war stories. Most time his father was not in the mood to talk about what he saw in the field, and didn't want his son to live the life he had been living for the past 20 years. Even so, Ilya pushed and pushed until his father conceded and told him about undercover missions he went on in foreign countries to incite insurgencies or take out targets that were threats to this country. This only fueled the imagination of the young boy. As soon as his father would leave, Ilya would take notes of his father's mission, and would try to enact them with his friends. This continued until he was 18, and conscripted in the Russian Army.
This was merely the beginning of a great military career.
After his year of conscription was over, Ilya, being the adventurous young man he was, decided to become like his father, and spend his life in the military. After a few months, he had already distinguished himself from the other soldiers in the RGF (Russian Ground Forces) , some officers came and told him he had a promising career in front of him, offering him a position in their rank. Quickly enough, he also distinguished himself in the Spetsnaz ranks. Serving in a multitude of foreign wars, his expertise grew and he became more and more like his father, which was great to him.
Until it wasn't.
Something interesting happened when he went home. This is where he decided to move away from his home and focus entirely on his career.
When he came home one day after taking care of an operation, he father was also there. The first this his father expressed is how much he was dissapointed in his son, and how he wished he had never told the stories of his operations. He proceeded to simply tell his son to get out, and to never come back. This broke Ilya's heart, but it made him redouble his effort. He no longer wanted to be like his father, he now wanted to be better then his father, and nothing would get between him and his new life goal.
One thing leads to another.
This is where Chernarussia comes in play. He was part of the of the few soldiers that made it through. He was assigned to go undercover and find out information, which he was great as now that he had all these years of experience behind him and now a lack of strings to anything besides his comrades. He was told by his commanding officer that if he managed to incite a insurgency, some promotion might very well be on the line. He stayed in the north side of the province while cutting most communication with his squad mates, keeping mostly to himself and living in his early years conditions. He made contact with gun dealers and people friendly to the Russian cause. Most of the pieces were in place.
And then it happened.
The infection had started and he learned about it pretty quickly. He made friends with the right people it seemed, and after contacting his CO, he was told the orders were still active, and he was to stay and to keep on informing the Russian army. He re-established contacts with his comrades and regrouped with them, making gun deals with his contacts and making sure most of his friends had weapons and supplies long enough to stay in the province for a while, until the supplies ran out at least. When the supplies ran out, and some of his squad mates were killed, he contacted his higher ups, and they told him to scavenge whatever they could and come back to the motherland for supplies and reinforcements, as well as new orders. He followed orders and sure enough, when they arrived at the rendez-vous, Russian military forces were waiting for them handing them supplies, including ammo, weapons, and clothing mostly civilian, still wanting to have an undercover op to be in effect. Alongside the supplies, they received a handful of men. They were told to head back to the province, but to focus most of their efforts on the northern side of the province. And that's just what they did.
