Ok a few quick tips is that the pre grenades and pre fire. What the key thing is to try to get a random frag grenade and the reason for the frag is so it rolls to them plus its good to cook for a coupla of seconds. Then the prefire is with the hardend perks on is when you dont really see the enemy but you know there and you just rapid fire in there or when you know when there coming around a corner and you just start firing. Then the main thing is too always walk around corners ready to fire and on defence never rush.

Now the killstreaks
#1: UAV Use this for one its hardcore so you need all the map as you can
#2: Napalm but you have to make sure you call out were you put it
#3: attack helicopter this is by far one ofthe best killstreaks on hardcore
