This report has been prepared for the purpose of explaining the technique used in compiling a series of maps showing the relative amounts of cold strain on the QM-equipped soldier in different environments. The maps were used primarily for indoctrination and display purposes to show the improvement in protection provided by the current standard cold weather clothing over that provided by the previous standard uniform. On the maps in Figures 1 and 2 representative of the series, the current standard clothing is referred to as the 1955 uniform, and the previous standard clothing is called the 1945 uniform. Major components of these uniforms are listed in Table I. The data on which the maps are based were derived by use of an equation developed by Dr. Douglas H. K. Lee, Office of RE, OQMG. By using this equation, it is possible to determine an index number G for cold strain, i.e, the effect of the environment on mans ability to keep warm under severe cooling conditions.
