Sandy - I know what an S-3 Journal is. I have a large file full of them. They are the radio messages that passed between the different units and individuals telling the other units where certain targets are, locating their own troops, some times mentioning individuals. Sometimes only units in code. Most places are in a numerical code. Often they refer to (if you could read the code) a bridge, stream, cross road, etc. The code is determined by placing a contractor like tool over a map from a designated center. The units are counted off in a certain manner and those #s are radioed to the units. Sometimes they require certan men to be at certain places at certain times but that is unusual in the ones I have.
They may be obtained with a request to NARA. If the price has not changed recently they are 50 cents a sheet. If you request them Nara will send you an invoice/order. You then decide if you want them and go from there.
The address is firstname.lastname@example.orgAllow two weeks for a reply and 4-8 wks for the invoice/order. Then another 4-8 wks for the material. Mary
