The Contras began to reorganize on the Honduran border under the direction of Somozist officers, with assistance from Argentine neo-Nazis by 1980, and US supervision from 1981. Nicaraguan exiles and Salvadoran army officers trace Salvadoran aid to the exiled Somozists to 1979, shortly after the fall of Somoza. Salvadoran pilots bomb Nicaragua under CIA control from their sanctuaries in Honduras and El Salvador, and according to US officials in Central America, fly as many as a dozen sorties a week from El Salvador deep into Nicaragua to supply contra forces. With CIA assistance, arms were smuggled from the US center for international terrorism in Miami, where the FDN leadership operates. CIA helicopters with American pilots provided air cover for commando raids, Ecuadoran frogmen were sent from CIA speedboats to blow up bridges, CIA transport planes dropped supplies to guerrillas deep inside Nicaragua, and a CIA "mother ship" launched seaborne commando raids to mine harbors. The Miami Herald reports that a secret US Army helicopter unit, a task force of the 101st Airborne Division operating out of Kentucky, is carrying out missions inside Nicaragua, with 17 fatalities in 1983 (35 casualties were reported by the entire US Army that year).
