not on the spot to act. Operating procedures were changed to provide for concentration on the high-incident areas at critical times. In large cities, tanks, armored cars, and jeeps of the Constabulary paraded in the streets in considerable numbers to show the Germans that the Americans meant business, and were properly trained and equipped to meet emergencies. Troopers' lives As the Constabulary trooper became accustomed to his duties, he gained more confidence and self-assurance. He possessed a thorough knowledge of police functions; he learned not to abuse his authority. No situation seemed insoluble. Consequently, two or three men could answer a call for assistance where formerly a section or more had gone out. In the Kaserne the trooper had the recreational facilities and comforts which constituted his home life in Germany—Service Men's Clubs with their snack bars and entertainments, motion pictures, American Red Cross facilities, and trans-Atlantic telephone service. The trooper whose family lived in a military community found living and recreation within his means. All members of the Constabulary and their families had the possibility of wide-ranging travel in Germany, France, Belgium, the Netherlands, Switzerland, and Italy. During the first six months of its activities the Constabulary made 168,000 patrols in jeeps, tanks, and armored cars, and on horseback and on foot. Its troopers traveled on these patrols more than five million miles, mostly in jeeps. The mileage covered by the vehicles of the United States Constabulary was equivalent to nine vehicles circling the earth every twenty-four hours. The mileage covered by foot patrols was equivalent to circling the globe once each week. The liaison airplanes of the Constabulary flew more than 14,000 hours on 11,000 missions during the first six months' period. In 1946, the Constabulary made many swoop raids, known officially as "check and search operations," against displaced persons' and refugees' camps and the German population. No raids were made unless requested by the United Nations Relief and Rehabilitation Administration, military commanders, military government, or investigative agencies which had reason to suspect black-market or subversive activities. The trooper operating in the municipalities was a deterrent to the individuals and groups who were the mainstay of the black market. In six months, 2,681 black-market transactions and 173 subversive acts were uncovered in Constabulary operations. The Constabulary assisted military government in the reorganization and development of the German police force. The Constabulary realized that its task would be greatly
