XDD the guy with the gernades he jump and the gernade blew him up so he could land no the building but the little sigh was not down so he went really high and can down, fell to his death Lol.
For the SD-6 you shoot the Ctp. let the guy thats talking to him, let him get away then look at the far left of your screen in the scope and shoot the guy with the machine gun, shoot him when he shows up :)
