Map: Invasion

Along the north of the map (pause game, up is north, right is east) is what players call the 'embassy' or 'fort'.

In the northeast corner is a Hummer. Jump onto that and climb through the window.

Also, in the northeast corner, go up the stairs, but before going inside, jump on a tiny ledge that goes all the way around the 'embassy'.

You can surprise people by shooting inside from the second story windows.

Be sure to push against the building as you run along this ledge as the window frames may knock you off otherwise.
