raiding activities. Aviation support was provided by both Marine air of the 15th MEU and 20th Special Operations Squadron. Several days before the beginning of the invasion, two SDV teams were launched from Mark V Special Operations Craft in the Persian Gulf. Their objectives were the hydrographic reconnaissance of the Al Basrah (MABOT) and Khawr Al Amaya (KAAOT) Oil Terminals. After swimming under the terminals and securing their Mark 8 mod 1s, the SDV SEALs spent several hours taking pictures and surveying Iraqi activity on both platforms before returning to their boats. On 20 March 2003, SEALs from SEAL Team 8 and 10 (31 SEALs, 2 Navy EOD a USAF combat controller and several Iraqi interpreters) moved to seize the MABOT oil terminal whilst GROM operators assaulted the KAAOT Oil Terminals. The terminals were quickly seized with no casualties, and explosives which were found on the terminals were made safe by GROM operators. The shore-based pumping stations (known as MMS-Monitoring and Meter Stations) and their pipelines on the Al-Faw Peninsula were seized by 12 SEALS from SEAL Team 3, who were mounted in DPVs. They took off from Kuwait and were inserted under Iraqi anti-aircraft fire by MH-53 helicopters. The target area was 'softened up' by JDAM bombs dropped from B-52s on Iraqi bunkers, trenches and dugouts around the oil facilities. After a brief firefight in which the SEALs killed 1 Iraqi soldier and captured 13, the SEALs secured the MMS and the pipelines and were relieved by Royal Marines from 40 Commando. The SEALs advised the Marines, helping coordinate AC-130 Spectres fire support onto Iraqi forces. The other shore-based pumping station at Umm Qasr was secured by SEALs and Royal Marines; before they landed, AC-130 Spectres and A-10As engaged a nearby SAM installation and a responding Iraqi mechanized unit. The SEALs secured the facility itself whilst the Royal Marines cleared Iraqi bunkers, killing several Iraqi soldiers. Other Naval Task Group operations included elements of three SEAL platoons in GMV trucks and DPVs seizing the al Zubayr MMS, whilst I MEF attacked the Rumaylah Oil Fields north of al-Faw. SEALs and Special Boat teams helped secure the Khawr Abd Allah and Khawr Az Zubyar waterways, which enabled humanitarian supplies to be delivered to the port of Umm Qasr. SEALs from the unit that secured the al-Faw MMS also conducted reconnaissance on the Shat Al Arab waterway, which was later secured
