small arms fire, as well as U.S. Air Force airstrikes. For the next five days, Iraqi forces continued to harass the Rangers at the dam, principally with episodic artillery and mortar fire along with several infantry counterattacks against the U.S. positions. The HIMARS rocket system saw its first combat deployment at the dam, firing counter-battery missions. Three Rangers were killed on 3 April by a VBIED at the blocking positions as they were searching a car; the car was driven by a young pregnant Iraqi woman who seemed distressed and asking for water. Later the Rangers captured an Iraqi forward observer dressed as a civilian after sinking his kayak with .50 caliber machine gun fire, the observer had maps of all of the Rangers positions in and around the dam. Aftermath Since the 2003 invasion, various U.S. Marine units had been stationed at the dam, as well as a small detachment of soldiers from Azerbaijan. In 2004, the Gulf Region Division of the United States Army Corps of Engineers (USACE) carried out restoration works on one of the turbines to restore the dam's hydroelectric power station to full capacity. According to the Coalition Provisional Authority, the inauguration of this turbine on 3 June 2004 signified the first time since 1990 that the power station operated at full capacity. In the same year, a new power line was established between Haditha and Baghdad with the help of the USACE to restore a line that had previously been destroyed. This new line, stretching over a distance of 223 kilometres (139 mi) with 504 towers, has a capacity of 400 kV and allows 350 MW from the Haditha Dam to be added to the national electrical grid. The cost of the line was US$56.7 million and was paid by Iraq's oil revenues. References Iraq War Battles of the Iraq War in 2003 April 2003 events in Asia
