What is the role of Major General Duane Gamble?

Major General Duane Gamble serves as the 21st Theater Sustainment Command (TSC) Commander. In this role, he is responsible for overseeing logistics and sustainment operations for the Army in theater, which includes managing supply chains, transportation, and maintenance support to ensure that Army units are fully equipped and supported in their operational tasks. The position of Commander of the 21st TSC is crucial for maintaining effective readiness and operational capability of forces in the region, coordinating efforts to facilitate the movement of troops and supplies as needed.

The other roles listed do not align with Major General Gamble's current assignment. For instance, the Sergeant Major of the Army is a senior enlisted position, which is not applicable to his rank and responsibilities. Similarly, the positions of CSM of the 39th Transportation Battalion and Commanding General of USAEUR pertain to different commands and roles within the Army hierarchy, which he does not hold. Therefore, identifying Major General Gamble as the 21st TSC Commander accurately reflects his role and contributions within the Army structure.
