New Use for the Aerial Reconnaissance Multi-Sensor (ARMS) Aircraft: How to Appropriately Use the ARMS Aircraft for Homeland Security without Infringement on the Posse Commitatus Act [open pdf - 433KB]
From the thesis abstract: "The Army Reserve Aerial Reconnaissance Multi-Sensor (ARMS) Aircraft are no longer required to provide overwatch in Iraq. With budgetary constraints, both the Department of Defense (DoD) and Department of Homeland Security (DHS) must employ fiscal responsibility by sharing assets. The ARMS aircraft can provide DHS similar overwatch capability as in Iraq, limiting the need for other more costly aerial assets and adding capacity. Additional mapping missions would increase operational reach for DHS. Such missions can be conducted without infringing on the Posse Commitatus Act by establishing proper control measures. Both DoD and DHS will benefit and show fiscial [sic] responsibility."
