THE STUDY INVOLVED FIELD TESTS BY PATROL OFFICERS IN 15 CITIES OF 5,000 GARMENTS, INCLUDING BODY ARMOR, DESIGNED FOR THE LEAA AS WELL AS COMMERCIAL ARMOR DESIGNS OF IDENTICAL BALLISTIC MATERIAL (KEVLAR 29). THE FIELD DATA WERE ANALYZED AND EVALUATED, AND MODIFICATIONS OF THE LEAA ARMOR, BASED ON FIELD TEST RESULTS, WERE IMPLEMENTED AND EVALUATED. THE STUDY TOOK INTO ACCOUNT THE EFFECTS OF FIT, COMFORT, AND HEAT CONTAINMENT ON GARMENT ACCEPTANCE AND WEAR, AND IDENTIFIED FACTORS IMPORTANT IN THE USE AND SPECIFICATION OF ARMOR. STUDIES TO CHARACTERIZE THE MECHANICAL AND BALLISTIC PROPERTIES OF KEVLAR 29 FROM A THEORETICAL POINT OF VIEW WERE CONDUCTED. GUIDELINES FOR PROCURING SOFT BODY ARMOR WERE DEVELOPED. THE FINAL REPORT OFFERS A COMPREHENSIVE DISCUSSION OF ALL TESTS, STUDIES, ANALYSES, AND EVALUATIONS, TOGETHER WITH DETAILS OF THE TEST DESIGN AND ANALYTICAL APPROACH, A SUMMARY OF THREE MEDICAL-TECHNICAL SYMPOSIUMS HELD DURING THE PROGRAM, REPORTS ON ALL INCIDENTS OR SHOOTINGS INVOLVING ARMOR, AND TECHNOLOGY TRANSFER ACTIVITIES CARRIED OUT AT THE END OF THE PROGRAM.
