Lynn, Fort Gordon's commanding general, was promoted in a relatively small and private affair of about 150 people in a cabin on the Army post's Leitner Lake Recreation Area not far from Harlem.
Lynn, who assumed command of the post after the retirement of Brig. Gen. Jeffrey Foley in July, called the promotion "humbling."
"This is a little bit overwhelming," the new major general said to a gathering that included his wife, daughter and parents.
Lynn acknowledged the role his father, retired Maj. Gen. Robert Lynn, played in his military career.
"Although I've walked in your footsteps, I can never fill your shoes," Lynn said to his father. "You're the best."
After the ceremony, Lynn said he has come to see Fort Gordon as much more than a training post for the Army's signal soldiers in his nearly seven months as commanding general of the post and the Signal Center.
Lynn said he also is overseeing a redesign of the Signal Corps that will change how commercial equipment is used by signal soldiers.
Moreover, he hopes to build pedestrian bridges over Chamberlain Avenue, the main road running through the post, to alleviate some congestion and make walking safer for everyone.
Before coming to Fort Gordon, Lynn was in command of the 311th Signal Command at Fort Shafter in Hawaii.
The major general is a veteran of the Gulf War, and commanded troops during Operation Joint Forge in Bosnia-Herzegovina in the late 1990s and during Operation Iraqi Freedom in 2004.
