In fact,in call of duty modern warfare is a mission where is a picture of lev kravchenko.In the others call of duty games:it is confirmed that captain price from call of duty 2 is grandfather of the actual.Reznov from call of duty world at war appears in black ops 1 and 2 so i can say yes.

But with call of duty ghosts i dont know,if is in the same universe maybe with call of duty modern warfare because mw3 ends in the year 2017 when Odin strikes.
