on the first and fourth pass. Rough Terrain Paratrooper

Most paratroopers landed within the boundaries of the drop zone and assembled in the South East corner of Luzon Tree Drop Zone. Numerous soldiers who landed in the trees found themselves suspended up to 40 feet above the ground. These soldiers rappelled to the ground by securing a letdown line to the risers of their MC1-1 steerable parachute. The Rough Terrain operation on 27 October was the first such operation conducted by the 57th Engineer Company since 2009. The purpose and intent of the Rough Terrain operation was to demonstrate the ability to land in a tree drop zone, and the proficiency to do so safely. The 57th Engineer Company is planning multiple Rough Terrain operations in 2012 in order to build proficiency, certify more soldiers as Rough Terrain, and continue to train the full spectrum of Rough Terrain operations. Training for the Rough Terrain operation was conducted at the United States Army Advanced Airborne School in September, 2011.{{cite web, last=Kuhn, first=Jessica, title=Rough Terrain paratroopers prepare for any landing at Rough Terrain Airborne Operations, url=http://paraglideonline.net/092211_news1.html, work=XVIII Airborne Corps PAO, publisher=Paraglide, accessdate=27 October 2011, url-status=dead, archiveurl=https://web.archive.org/web/20120425045739/http://paraglideonline.net/092211_news1.html, archivedate=25 April 2012
