Volunteers, led by U.S. Air Force Senior Master Sgt. Russell Weatherby, 17th Security Forces Squadron individual mobilization augmenter, march the perimeter road during the Jacobson ruck march on Goodfellow Air Force Base, Texas, Sept. 28, 2017. Jacobson was killed in action on Sept. 28, 2005, on patrol near the Iraqi town of Safwan. Her vehicle was hit by an improvised explosive device, killing her and U.S. Army Sgt. Steve Mornin. She was the first security forces Airman and first female Airman to die in Operation Iraqi Freedom. Weatherby led Jacobson’s fire team and was present the day it all happened.
