Description Solid Shield in May 1987. This exercise simulated a United States response to a request from Honduras to help fight a Nicaraguan invasion, and it coincided with larger United States military exercises carried out on the Puerto Rican island of Vieques and at Camp Lejeune, North Carolina. The Honduran phase of this operation involved more than 7,000 United States military personnel as well as 3,000 Honduran soldiers. As part of the exercises, a combined air and sea landing in Honduras was undertaken by a brigade of 3,000 helicopter assault troops from the 101st Airborne Division at Fort Campbell, Kentucky, and a marine amphibious unit of 1,800 from Camp Lejeune. These maneuvers tested the ability of the army, navy, marine corps, air force, and coast guard to mobilize and operate together in a large-scale operation, which was also meant to help train and build a logistical infrastructure for the Contras based in Honduras. Daniel José Ortega Saavedra, who was then the president of Nicaragua, accused the United States of planning an invasion of his country.
