The Rope Ladder can be
deployed in places like windows. This comes in handy if you can't get into a building using
doors, so you have to use the Thief to climb the wall, and go through a window. If you want
the other Commandos in the same building, but because they can't climb, drop the ladder out
the window, and now the rest of the team can get there too.
TIP: The Ladder can be rolled up and used again, so don't forget
it.
