Chapter V V-28 JP 3-0 Grenada 1983, to protect US citizens and restore the lawful government). Raids end with a planned withdrawal upon completion of the assigned mission. f. Homeland Defense and Defense Support of Civil Authorities. Security and defense of the US homeland is the USG’s top responsibility and is conducted as a continuous cooperative effort among all federal agencies as well as state, tribal, and local government. Military operations inside the United States and its territories, though limited in many respects, are conducted to accomplish two missions—HD and DSCA. HD is the protection of US sovereignty, territory, domestic population, and critical defense infrastructure against external threats and aggression or other threats as directed by the President. DSCA consists of DOD support to US civil authorities for domestic emergencies and for designated law enforcement and other activities. Requests for federal assistance of this nature must be submitted to the DOD Executive Secretary. (1) Homeland Defense. The purpose of HD is to protect against and mitigate the impact of incursions or attacks on sovereign territory, the domestic population, and critical defense infrastructure. DOD is the federal agency with lead responsibility, supported by other agencies, in defending against external threats/aggression. However, against internal threats DOD may be in support of an OGA. When ordered to conduct HD operations within US territory, DOD will coordinate closely with OGAs. Consistent with laws and policy, the Services will provide capabilities to support CCDR requirements against a variety of threats to national security. These include invasion, CNA, and air and missile attacks. OPERATION EL DORADO CANYON The strike was designed to hit directly at the heart of Gaddafi’s ability to export terrorism with the belief that such a preemptive strike would provide him “incentives and reasons to alter his criminal behavior.” The final targets were selected at the National Security Council level “within the circle of the President’s advisors.” Ultimately, five targets were selected. All except one of the targets were chosen because of their direct connection to terrorist activity. The single exception was the Benina military airfield which based Libyan fighter aircraft. This target was hit to preempt Libyan interceptors from taking off and attacking the incoming US bombers. The actual combat commenced at 0200 (local Libyan time), lasted less than 12 minutes, and dropped 60 tons of munitions. Navy A-6 Intruders were assigned the two targets in the Benghazi area, and the Air Force F- 111s hit the other three targets in the vicinity of Tripoli. Resistance outside the immediate area of attack was nonexistent, and Libyan air defense aircraft never launched. One F-111 strike aircraft was lost during the strike. Various Sources
