northern Iraq. On 22 March, another F-15 destroyed a second Su-22 and the pilot of an Iraqi PC-9 trainer bailed out after being approached by US fighter planes. On 5 April, the United Nations Security Council passed Resolution 688, calling on Iraq to end repression of its civilian population. On 6 April, Operation Provide Comfort began to bring humanitarian relief to the Kurds. A no-fly zone was established by the US, the UK, and France north of the 36th parallel, as part of the Iraqi no-fly zones. This was enforced by US, UK, and French aircraft. Included in this effort was the delivery of humanitarian relief of over an estimated 1 million Kurdish refugees by a 6-nation airlift operation commanded from Incirlik Air Base Turkey involving aircraft from the US, UK, France, Germany, Canada, and Italy. Soviet aircraft participated in logistical aspects of the operation. The airlift was commanded by Colonel Dave Wall, Wing Commander, Aviano Air Base, Italy. Intel and Planning Section Chief was Lt. Colonel Mike DeCapua who coordinated drop zone locations and unique aircraft loads. During the 31-day airlift, more tonnage was delivered and more air miles flown than in the entire Berlin Airlift. C-130s and other transport aircraft flew air drop missions under AWACS control with A-10s and F-16s providing air and ground fire support for the airlift aircraft. On several occasions A-10s neutralized Iraqi radar units in the Zaku area. Units of the 18th Military Police Brigade, commanded by Colonel Lucious Delk, and a forward Headquarters Command Cell led by Captain Alan Mahan, and Sergeant Major Ed Deane, with units of the 709th Military Police Battalion, the 284th Military Police Company and the 527th Military Police Company, provided security of the headquarters, Kurdish refugee camps, and convoy security. The brigade was the last unit to leave the area at the conclusion of operations. Several members received the Soldier's Medal after calling in and assisting in the medical evacuation of a wounded Iraqi citizen from a minefield near the river not far from the MP headquarters camp. While Operations Desert Shield and Desert Storm were run by the US Central Command (CENTCOM), Operation Provide Comfort came under the authority of the US European Command (EUCOM), headquartered in Vaihingen, Germany. On-ground humanitarian aid was provided by the 353rd Civil Affairs Command commanded by BG Donald Campbell, and by its subordinate units, 432nd Civil Affairs Battalion, and 431st
