FORT LEAVENWORTH, Kan. - The Georgia-based 3rd Infantry Division and California-based National Guard 40th Infantry Division conducted warfighter exercises at Fort Stewart, Georgia, and Camp Atterbury, Indiana, supported by the Mission Command Training Program.

The Nov. 5-14 exercises were part of an ongoing series of division-level exercises with regular Army and Reserve Component elements training side-by-side to build proficiency and readiness to conduct multidomain operations in large-scale combat operations.

Gen. James McConville, chief of staff of the Army, suggested the importance of the two components training together at a recent National Guard conference.

“We [the regular Army] don’t go anywhere or do anything without the National Guard,” he said. “We cannot do what we do as an Army without the National Guard.”

The 3rd and 40th Infantry Division elements simulated operating as adjacent divisions, charged with expelling an invasion force from an occupied allied country.

The scenario allowed them to practice pacing offensive operations as adjacent units within their respective sectors to limit potential vulnerabilities on their flanks. They also worked on coordinating cross-boundary and deep-area support and sharing information to round out each element’s understanding of the situation.

The exercise proved timely and operationally relevant.

It occurred amid the official announcement of the 3rd Infantry Division’s Combat Aviation Brigade deployment to Europe as part of the Atlantic Resolve mission.

Atlantic Resolve began in 2014 with the U.S. providing rotational deployments of combat-credible forces to Europe to show its commitment to NATO and strengthen interoperability, according to U.S. Army Europe and Africa sources.

The 3rd CAB honed its ability to support division-level operations in the exercise ahead of its deployment.

MCTP’s warfighter exercises are emerging as the Army’s go-to combat training center rotations for readying echelons above brigade and functional and multifunctional brigades ahead of deployments.

The Colorado-based 4th Infantry Division headquarters and its sustainment brigade also completed warfighter exercises in October. They deploy to Europe in 2023, with the 3rd CAB aligned under their command and support in Europe.

The 40th Infantry Division brought a unique perspective to the exercise. It has significant expertise in urban operations, having conducted real-world support missions in California in highly urbanized cities such as Los Angeles. It also leads an urban planners’ course and recently partnered with the National Training Center in Fort Irwin, California, to enhance the urban terrain it replicates in its training areas.

Their perspective gave them a keen sense of civilian considerations and led to a focus on precision targeting in their area of operations.

The exercise enabled them to train on complementary skills of facing a near-peer threat in less densely populated areas, akin to some operations in Ukraine.

The California National Guard, from which the 40th hails, has a state partnership with Ukraine. 

The 3rd Infantry Division also had a connection to the conflict in Ukraine. One of its brigade combat teams deployed to Europe on short notice as soon as the invasion began. It supported Joint Task Force Dragon to assure NATO allies and partners in the region.

“Soldiers of the 3rd Infantry Division regularly deploy to support combatant commands all over the world, assisting our allies and partners in a wide range of environments and missions,” said Col. Pete Moon, 1st ABCT, 3rd Infantry Division commander.

The brigade had only recently returned from its deployment before the exercise began.
