This report documents the methodology used and the results of a computerized photosimulation evaluation to quantify the military effectiveness of various camouflage patterns across different environments. The evaluation was conducted by the U.S. Army Natick Soldier Research, Development and Engineering Center (NSRDEC) between March 2007 and March 2009. This study extended a digital blending evaluation conducted by NSRDEC in 2006 of two different camouflage patterns in a given environment to multiple environments. The photosimulation evaluation technique used was developed by NSRDEC in collaboration with the Aberdeen Test Center in 2008. The objective was to evaluate the detection performance of camouflage patterns by obtaining visual R50 values (range for 50% probability of detection) for a total of 18 standard, foreign and experimental camouflage patterns in various terrain environments under daylight conditions. Probability of detection data were collected from 913 observers. The data clearly show that environmentspecific patterns provide the best camouflage, i.e., the lowest probability of detection, in their respective environments. Recommendations for further analysis of the data are included in the report. 15. SUBJECT TERMS
