Strategic Managers and Leaders- 1 1/2 page paper

It has been said that strategic leaders are concerned with vision and mission, while strategic managers are concerned with strategy. Do you agree? Your answer should include specifics about what you believe a strategic leader does as opposed to what a strategic manager does (e.g., analyze competitors, review market analysis, become informed on technological trends, etc.). In addition, discuss whether you feel there is a need for both roles in organizations today. Justify your answer.  (A 1½-page response is required.)  Must be in APA format with references.
