Doesn't remember anything besides his name and his early life before joining S-GRU at 22 years of age. Wakes up in Chernarus amongst smoking gore and bodies, never got the smell of blood out of his nose since then. Trying to survive using skills he doesn't know how he got them (Between us, from the training and experience as an S-GRU operative of course). He's trying to survive and find back his memory. The first is easier than the second because he has no leads besides being in a helicoper filled with covert S-GRU operatives, meaning they didn't carry papers nor wore military outfits. All he has is a picture of his wife in a medallion around his neck, which he now actually carries in his pocket (spoiler) because he strangled a survivor who held him up.
