THIS UNCLASSIFIED STUDY, DESIGNED FOR DISTRIBUTION TO U.S. MILITARY PERSONNEL ASSIGNED TO OR CONTEMPLATING AN ASSIGNMENT TO THE EUROPEAN THEATER, PRESENTS AN ENCYCLOPEDIC LISTING OF TERRORIST GROUPS OPERATING IN THE UNITED KINGDOM, IN THE MIDDLE EAST, AND ON THE CONTINENT OF EUROPE. GROUPS WHICH MAY POSE A THREAT TO U.S. INSTALLATIONS OR PERSONNEL ARE HIGHLIGHTED. THE STUDY IS ARRANGED ALPHABETICALLY BY COUNTRY AND ALPHABETICALLY BY GROUPS WITHIN THAT COUNTRY. (THE EXCEPTION IS THE MIDDLE EAST, WHICH IS TREATED AS AN ENTITY RATHER THAN BY SEPARATE COUNTRIES.) FOLLOWING A SHORT DESCRIPTION OF THE POLITICAL CLIMATE IN THE COUNTRY AND OTHER BACKGROUND INFORMATION, EACH GROUP IS DESCRIBED BY SIZE, PERSONALITIES, MODUS OPERANDI, WEAPONS, SIGNIFICANT OPERATIONS, OPERATIONS DIRECTED AGAINST U.S. FACILITIES OR PERSONNEL, AND EVIDENCE OF COOPERATION BETWEEN GROUPS. SOME CHAPTERS ALSO CONTAIN A LIST OF LESSER-KNOWN GROUPS. A BIBLIOGRAPHY CLOSES EACH CHAPTER. COUNTRIES DISCUSSED INCLUDE CYPRUS, FEDERAL REPUBLIC OF GERMANY, FRANCE, GREECE, IRAN, ITALY, THE MIDDLE EAST, THE NETHERLANDS, PORTUGAL, SPAIN, TURKEY, AND THE UNITED KINGDOM. A FINAL CHAPTER DISCUSSES TRANSNATIONAL LINKS AMONG TERRORIST GROUPS. (GLR)
