A controversial hard-liner in the guerrilla war against Nicaragua's leftist government has become the first military man to win a key role in the rebel leadership. Col. Enrique Bermudez, who survived an ouster attempt in April, joins a seven-member Contra directorate that oversees the U.S.-backed insurgency against the Sandinista government. The 56-year-old professional soldier, a former colonel in the Nicaraguan National Guard under ex-dictator Anastasio Somoza, was elected by a 44-2 vote Monday by an assembly of rebel delegates meeting in Santo Domingo, Dominican Republic.
