Has anyone else had problems getting the Backstabber medals? I'm trying to get Ghost Pro but the game is very particular about what it considers a knife to the back.
Also how do you get credit for destroying a sentry gun to get Ghost Pro? I destroyed two last night - one with a LAW and one with semtex.
I experienced the same thing with the backstabber medals. I had a few times I got directly behind the person, stabbed them and never got credit. The one I got it on, the guy was actually more towards the side and it gave me credit for stabbing him. Just keep trying.
I destroyed the Sentry gun with a Galil. I first threw a frag at it, which did not destroy it.. but I finished it off with the gun and got the credit for it.
A side story about how I got it.... I tried for days, the entire time playing trying to destroy a sentry to get Ghost Pro. No one was ever using and/or getting a sentry gun as a killstreak. So I followed what someone said on this thread, and bought it myself. When I would get the kill streak, I would try to run into the enemies spawn and throw it at them so they would take it. Morons never would, and if they did they would never set it up so I could destroy it. Most of the time my teammates would go and get it, even with me on the mic screaming at them to leave it alone. So I had given up, thinking it was never going to happen. I decided to work on flak jacket pro instead. The next game I joined, the team I was on was getting destroyed by a Sentry gun, and I spawned right beside it. I destroyed it, hoping I still had ghost on my load out.... luckily I forgot to change the perk and I still had ghost on. By sure chance I finally got ghost pro. Which I love, and team mates love especially if the enemy gets a Huey. I take it down pretty quick as they are all getting slaughtered.
