The School of Advanced Military Studies (SAMS) is one of four United States Army schools that make up the United States Army Command and General Staff College (CGSC) at Fort Leavenworth, Kansas. This "enormously rigorous" graduate school comprises three programs: the larger Advanced Military Studies Program (AMSP); the Advanced Strategic Leadership Studies Program (ASLSP), a Joint Military Professional Education II (JPME II) certified senior service college program for senior field-grade officers, and the Advanced Strategic Planning and Policy Program (ASP3), which supports officers in obtaining doctorates from civilian schools.
