This bill directs the Secretary of Defense to modify Department of Defense Instruction 5111.20, which governs the State Partnership Program . These modifications are intended to refine the selection analysis for new partnerships under the program. Specifically, the bill requires the Chief of the National Guard Bureau to consider the total number of current partnerships assigned to a State's National Guard. Furthermore, it mandates that preference be given to States that currently have only one active assigned country under the State Partnership Program, aiming to distribute partnerships more broadly among states.
