Long range identification of five vehicles was studied in a laboratory experiment. Silhouette pictures, with high contrast, were viewed at scaled ranges from 3000 to 7200 m. Subjects made 160 observations each. For all vehicles the mean rate of correct identifications was over 50 % up to 5000 m. At longer ranges the differences in performance between the vehicles increase and there is a significant interaction between vehicle and range. At ranges over 5000 m there is a clear tendency to underestimate the target size. It is concluded that the composition of the target array is of great importance for the identification performance. Methodological implications of this are discussed.
