From the Battlefield to the Pentagon: Colonel Gregory Tomlin on Leading Army Transformation

During his 24-year tenure in the Army, Colonel Gregory Tomlin has seen his fair share of transformation efforts. A career Field Artillery officer, he has served in four divisions—the 1st Armor, 1st Infantry, 2nd Infantry, and 7th Infantry—and commanded both M109A6 and M777 units. His operational experience spans deployments to Iraq, where he served as a rifle platoon leader and later as a military advisor, and Kosovo, where he was task force Information Operations officer.

Beyond command, Colonel Tomlin has held key staff assignments on the Army and Joint Staff, including Chief of Targeting Doctrine and Policy on the Joint Staff J-2 and Chief of Army Readiness in the Army Staff G-3/5/7. He has also served as a White House Military Social Aide during the Obama administration and as an assistant professor of history at West Point. In July 2024, he assumed his current role as Army Capability Manager for Division Artillery Formations.

Now, with a new administration in the White House and new leadership in the DoD, Colonel Tomlin is embracing the latest Army Transformation Initiative, which includes plans to modernize the force, increase lethality, and restructure formations. In the latest interview from IDGA, Colonel Tomlin sat down to share his role in the Army’s Transformation Initiative as well as the value of international collaboration, and much more. The views he expresses are his own and do not necessarily represent those of the U.S. Army or the Department of Defense.
