• US Defense Secretary Pete Hegseth to announce 20% cut in senior officer positions.
• The cut affects generals and admirals, one- to four-star officers.
• Hegseth plans to reshape the department by changing job ranks and canceling billets.
• The move follows a 20% reduction in four-star officers last year.

This announcement may signal a significant shift in the Pentagon's leadership structure, which could impact the department's overall efficiency and effectiveness. The reduction in senior officer positions suggests a focus on streamlining operations and reducing bureaucracy, which may have implications for the military's ability to adapt to changing global security threats.
