On the evening of March 26, 2003, a DEVGRU assault element supported by B Company, 2nd Battalion, 75th Ranger Regiment at a complex known as al Qadisiyah Research Centre - codenamed Objective Beaver - that intelligence indicated that chemical and biological weapons stocks may have been located along the shore of the al Qadisiyah reservoir among government and residential buildings, assaulted the complex (codenamed Objective Beaver). Whilst the first of four MH-60Ks inserted the Rangers into their blocking positions, it was engaged by small arms fire from a nearby building, an AH-6M spotted the muzzle flashes and fired a 2.75inch rocket into the location silencing the small arms fire, the second MH-60K was also struck by small arms fire but its door gunner suppressed it. USAF A-10A Thunderbolt II "Warthogs" engaged nearby electricity transformers successfully blacking out the area, but it resulted in a series of explosions and a resulting fire at the stations that dramatically lit the sky - pinpointing the orbiting helicopters from enemy gunmen. Small arms fire increased as the final two MH-60s inserted their blocking teams, the two pairs of AH-6M Little Birds and MH-60L Direct Action Penetrator Blackhawks, supporting the mission continued to suppress targets as the four MH-47E Chinooks carrying the DEVGRU main assault force inserted under heavy enemy small arms fire whilst DEVGRU sniper teams aboard a pair of MH-6M Little Birds engaged numerous gunmen and vehicles. The SEALs conducted a hasty SSE while the Ranger blocking positions received and returned fire, the AH-6Ms and the aerial snipers continued to engage enemy gunmen whilst the DAPs pushed further out to ensure no reinforcements approached - engaging and destroying numerous Fedayeen armed technicals. The SSE took longer than expected owing to the size and maze-like structure of the building, the mission completed after 45 minutes, later tests of the material recovered by DEVGRU showed no evidence of chemical or biological weapons at the Objective Beaver, one Nightstalker crew from an MH-47E and one Ranger was wounded. On April 1, 2003, around 60 SEALs from DEVGRU successfully rescued PFC Jessica Lynch from a hospital in An'Nasiriyah.
