This United States Army War College Department of Command, Leadership, and Management manuscript, Strategic Leadership Primer for Senior Leaders Fourth Edition, is a guide along the journey of alignment of your competencies with the demands of the environment in which you now lead. It begins with an understanding of how the environment differs from the organizational to the strategic levels, then follows with the differences in roles and competencies that strategic leaders require. It concludes with a way ahead for leaders to establish their own professional development plans. It is useful as a resource for both War College students to learn about entry into the strategic level, and for graduates immersed in the environment who need a tool to get past the tyranny of the inbox and think longer-term, as strategic leaders should.
