Location
When you start the level, go through the door and kill the Grunt there. Backtrack and right above the first door you came through there is a light. Crouch Jump onto that and either Crouch Jump or Grenade Jump again (Crouch Jumping is easier), and you should be on the roof (or you can get the Sputnik Skull and only use one grenade). Look for a space between the two buildings, and go into it, at the end there should be four Fragmentation Grenades, a spotting scope, and the Skull in front of them.
