"Attention Soldiers! The latest version of America's Army Special Forces (Overmatch) is now available. This version includes ES2 updates to four classic maps: SF Courtyard, SF Hospital, Urban Assault and Bridge Crossing. These updated missions will require you to identify ES2 designated objects and report the object locations to your Squad Leader."

For the moment no patch from version 2.8.4 to 2.8.5, need to use the Deploy Client, take a look into the download section of the site to find it.
