Which officer is the 264 Medical Battalion Commander?

The 264 Medical Battalion Commander is LT. COL Martinez because this role is typically held by an officer with the rank of Lieutenant Colonel or higher. In a battalion, the commander is responsible for overall leadership, strategy, and mission execution, which aligns with the expected authority and responsibility level associated with the rank of Lieutenant Colonel.

In a military hierarchy, the roles of other ranks mentioned, such as the First Sergeant, Colonel, and Command Sergeant Major, are distinct from that of a battalion commander. While COL Menendez holds a higher rank, he is likely in a different command position rather than commanding the 264 Medical Battalion specifically. 1SG Tucker serves as the first sergeant, focusing primarily on the daily operations and welfare of the soldiers within the company, and CSM Wright, as a command sergeant major, supports the battalion commander but does not command the battalion itself. Thus, LT. COL Martinez is correctly identified as the battalion commander due to the alignment of rank and responsibilities.
