Instead, hang on the outskirts, using the nearby columns for cover as you drop the insurgents. The post is visible, but don't try to take it yet. Once this is taken (it shouldn't be guarded heavily), move down the opposite stairs and begin working the courtyard. Your goal is to get to the staircase just beyond the fountain, where the first post can be found-The Office. When the battle begins, move right and slay whatever's in your path. Begin at the edge and work at them in a row. There are only three command posts to overtake in this map, and they're all pretty easy to manage.
