Ground Branch was placed in charge of the ground war. This is a testament to SAD being the preeminent force for unconventional warfare and their long-standing relationship with the most effective fighting force in the region, the Kurdish Peshmerga. Pakistan SAD/SOG has been very active "on the ground" inside Pakistan targeting al-Qaeda operatives for Unmanned Aerial Vehicle (UAV) Predator strikes and along with USSOCOM elements they have been training Pakistani paramilitary troops and regular Army troops, they have also done HVT target missions alongside Pakistani special forces. Before leaving office, President George W. Bush authorized SAD's successful killing of eight senior al-Qaeda operatives via targeted air strikes. Among those killed were the mastermind of a 2006 plot to detonate explosives aboard planes flying across the Atlantic Rashid Rauf and the man thought to have planned the Islamabad Marriott Hotel bombing on September 20, 2008, that killed 53 people. The CIA Director authorized the continuation of these operations and on January 23, SAD/SOG performed killings of 20 individuals in northwestern Pakistan that were terrorists. Some experts assess that the CIA Director – at that time Leon Panetta – has been more aggressive in conducting paramilitary operations in Pakistan than his predecessor. A Pakistani security official stated that other strikes killed at least 10 insurgents, including five foreign nationals and possibly "a high-value target" such as a senior al-Qaeda or Taliban official. On February 14, the CIA drone killed 27 taliban and al-Qaeda fighters in a missile strike in south Waziristan, a militant stronghold near the Afghan border where al-Qaeda leaders Osama bin Laden and Ayman al-Zawahri were believed to be hiding. According to the documentary film Drone, by Tonje Schei, since 2002 the U.S. Air Force 17th Reconnaissance Squadron has been working for the CIA as "customer", carrying out at least some of the armed missions in Pakistan. In a National Public Radio (NPR) report dated February 3, 2008, a senior official stated that al-Qaeda has been "decimated" by SAD/SOG's air and ground operations. This senior U.S. counter-terrorism official goes on to say, "The enemy is really, really struggling. These attacks have produced the broadest, deepest, and most rapid reduction in al-Qaida senior leadership that we've seen in several years." President Obama's CIA Director Leon Panetta stated that SAD/SOG's efforts in Pakistan have been "the most effective weapon" against senior al-Qaeda leadership. These covert attacks have increased significantly under President Obama,
