Security considerationswon out and a system of using four dj.@t s~ppi~ desi~ators to represent individual islands in Miwetok Ato~, and one for Kwj~ein numerical desi~tions waa devised. The were obtained f~m a list of euch designators maintained and assi~ed by the Do~rtmt of the Army. This system is the standard one for mark~g used for classified Army and Air Force movements. The Air Transport Cormnatimade strong representationsto uee ‘finthe cl.earnmarkings. This was over-ruled for security considerations. In addition, a dual systemof narkings would have made -$ . diversion from water to air or air to water impracticable without cow pletely remarking containers. It was directed that a green ~X’1would be painted on each container. There was some objectionby J-2 to this procedure. However, it was considered necessary to clearly designate all Sandstone supplies, which would be nmving through large supply installations,in order that they would not be mis-shipped. This marking proved invaluable to the out-loading ports as later experience was to show. 6. Subject Letter, “Procedures for Obtaining Project Material “ * / and Equipment published 16 October 1947.
