Wait for the dilevery man to come and pick the grocery crate and wack him with the fibre wire. Then take his clothes and the grocery crate. Head to the building on the right with flag in front and lots of guards. Go to the left side of the building and enter the kitchen. Talk to the cook and take the laxative and apply it to the pot. After Mr. Fuchs enters the restrooms follow him and kill him with the silenced pistol. Wear his clothes and exit the restrooms. Follow the soldier to the train and ride with him. When it stops go south to the ship and follow the directions of the guards to reach the commander. Of course you should drop your weapons before standing for inspection in front of the commander room. Enter the commander room and kill him when he turns to drink vodka. Take the master key and go left and open the door. Go down util you come to the main entrance of the ship. Go to the second door on the left where there are three soldiers and immediately to the door behind them. Pick the three bombs then exit the ship and go to the submarine. Go to the ladder and climb it down to the ice surrounding the submarine. Place the bombs where the exclamation marks are and return to the ladder and go away from the submarine and detonate the bombs. Make sure the guard patroling away from the submarine is close enough to be blown by the explosion otherwise, he will discover dead bodies and a warning will be displayed. Go back to the train and ride it back to the airplane and fly it to end the mission.
