Mission 5: Washington Monument
This is a perfect mission you get your tough PEC no firing, no being seen challenges. Just know that you can EMP and still get it.
Start by following the first guy into the dark on the right and grab him.
Head out the right side and then wait for the second guy to pass you and then follow him into the dark straight ahead.
Third guy will pass in front of you again and following him around to the dark.
Then head into the monument office to meet Vic and get some gear.
Head back into the fair on the right under the trailer and been low and quick to not get seen. Then go to the far right side and wait until the three guys leave to jump over and move on to the right. Roll all the way to keep from getting seen. Then hug the right side of the Mob game and wait for that guy to walk away. Go around low to the right behind the grill and jump over. Left under the trailer and to the far right again. Wait for a guy to come on the far left and when he leaves blast the EMP and jump over and roll hard right to the small outcropping. Wait for the guy in that area to walk away and go left hugging to top to a small fence. Jump it and hug left to get down to the grass. Far back left and jump the bench and you can slip right by the two guys standing there.
