Dolan's second tour occurred from May to November 2004 during the Iraq War. On this deployment, VMA-542 was stationed at Al Asad Airbase in the Al Anbar Governorate. She was assigned as the weapons and tactics instructor for the squadron and led combat missions in multiple battles including Operation Phantom Fury—the Second Battle of Fallujah. Dolan returned home and served as the group's safety officer. She attended school with Training and Education Command in Quantico, Virginia but ultimately decided to leave active duty for the Marine Corps Reserve and a civilian position at General Electric. During her 12 years of active duty service, Dolan flew 121 combat missions in the AV-8B.
