Can the Army sustain its current tempo of overseas deployments without reaching the breaking point? The nation has difficult trade-offs in facing calls on Army forces for operations in Iraq and Afghanistan. This report describes the effects of large deployments on the Army's ability to provide forces for other contingencies, to ensure that soldiers are trained, and to continue to recruit and retain soldiers. The authors found that Army plans for transformation and employing reserves at reasonable rates still fall short. Steps to improve the situation all involve high risks or costs. Unless requirements recede, the nation faces an Army stretched thin, with no quick fix or easy solution.

This report describes the mathematical model SAGE-A (Safety Assessment of the Ground Environment of Airports), which was developed as a general tool to evaluate the crash risk to populations living in close proximity to airports and to evaluate various policy options for mitigating this risk.
