From the student monograph abstract: "This monograph examines two critical issues: one, guerilla [sic] air war; and two, whether or not the existing US Army AMD [Air and Missile Defense] structures can meet the challenge of such attacks and defeat them at the tactical level. The US Army has recently removed all tactical level AMD units. Army maneuver commanders do not possess organic surface to air systems that would enable them to engage current air threats from a guerilla air war. The US Army's AMD force has prepared for operational threats like TBMs [Tactical Ballistic Missiles], but these systems are judged to have limited value to the tactical commander. The monograph concludes with the argument that the removal of AMD units from the tactical level has left the Army dangerously and unnecessarily weak in certain respects."
