Going up this part without killing any soldiers is pretty hard. Luckily, if you have enough stun grenades this part is a breeze. While climbing you should count the flights of stairs that it will take to use a stun grenade. I count 7 flights and toss my first one, then 4 flights, then I keep on tossing them depending on the time it takes for the guard to get back up.
