Passage: The group was occasionally diverted from strategic missions to carry out air support and interdiction missions. It supported Operation Overlord, the invasion of Normandy by attacking transportation targets, including bridges, along with airfields and strong points in France. On D Day, the squadron and the rest of the 446th Group led the first heavy bomber mission of the day. The 446th aided ground forces at Caen and Saint-Loduring July by hitting bridges, gun batteries, and enemy troops. During Operation Market Garden, the attempt to seize a bridgehead across the Rhine in the Netherlands, the 704th dropped supplies to allied troops near Nijmegen. It struck lines of communications during the Battle of the Bulge. During Operation Varsity in March 1945, it supplied ground and airborne troops near Wesel.

Question: How long was Leon Panetta Secretary of Defense? Passage:Due to his actions during the battle, former Army Captain William D. Swenson was recommended to receive the Medal of Honor by Marine General John R. Allen. Having been critical of the officers superior to him during the battle, he left the Army in February 2011. A 2012 investigation by McClatchy News Service concluded that the justification for Meyer's decoration may have been inflated and that the nomination for Swenson's Medal of Honor may have been intentionally lost. Meyer disputes McClatchy's allegations in his book, Into the Fire: A Firsthand Account of the Most Extraordinary Battle in the Afghan War. In August 2012, California Representative Duncan D. Hunter wrote to Secretary of Defense Leon Panetta regarding the Medal of Honor nomination of Swenson, comparing his case to that of Sgt. Rafael Peralta. In January 2013, Representative Hunter said Swenson's nomination had been awaiting President Barack Obama's approval at the White House since at least July 2012. Representative Hunter stated he was considering seeking an inspector general inquiry due to the delay. Swenson was awarded the Medal of Honor on October 15, 2013.
