Defense Budget: Army National Guard Operation and Maintenance Budget

Pursuant to a congressional request, GAO identified the reasons for the Army National Guard's unfinanced Operation and Maintenance (O&M) requirements, focusing on the: (1) way the Guard prepares its O&M budget; (2) five Army models the Guard uses to generate most of its O&M requirements; and (3) improvements the Army and the Guard are making to correct problems in their use of the models.
