Target Area 164 Charlie.
Grid 201 500 achieved by dividing the Charlie square into 100 additional squares and read from the bottom left up (IE. 201) then across to the right (IE. 500). So the exact target would be slightly over 2/10ths of the way up and centered to the right at that point inside of that Charlie square. Sound okay?

    That, too, makes sense George. The closest I can get to understanding how the alpha numeric coordinates are referenced is this target map from Iwo Jima. It makes sense that there are alpha squares... more

        I remember that clue from Map Reading training at Quantico in the late 60's. I sent Tom attachment of my Map. Semper Fi, Don

          Thanks Don! This is pretty cool. More to chew on here. Looks like Lt Greene used the back to spot gunfire on the back of map. I understand what George sent on Iwo map and it makes perfect sense but... more

        Sorry - got that backwards. The coordinates should be read to the right and then up. Not up and to the right. So, 201 500 would be just over 2/10ths to the right and then half-way up the Charlie... more

          Thanks, George! I obviously am not a candidate for cryptographic corps :) I will need to absorb this. Still looks like the Tarawa map would require additional detail to zero in on an area.
