Abstract
The legibility of selected military map symbols on a CRT display was determined by testing a symbol set of nineteen primary role descriptors symbols for military units using a tachistoscopic presentation technique. Simpler geometric symbols composed of fewer line components were more quickly recognized than complex ones, and were also the source of fewer errors. Symbols with circular or curved components were more likely to be confused with each other than with symbols composed of linear components.
