you were on a mission and you were far behind because you were injured and out of breath and you collapsed far back as nobody knew but then a American soldier captured you and held you close to him and his teammates as the russian army realized they had you and they were pissed at the Americans because you are the generals son (Makarovs son)

RS 1: let him go you bastards! RS2: If you hurt him we'll kill you! Russian soldiers: LET HIM GO
