Ae presently written In. Ogle will be able to disequgsa only three shate (LACROSSE, GHEROKEE, plus the shot observed) from the table. Since these will give a very incomplete picture of Gperation RELWING we suggeat Ir. Ogle be antherised to present the entire table but with the dates of the shote deleted and the “Approximate fxpected Yield" replaced by the following: ‘Low EE* (Less than 100 XT) “High KEY (160-999 KT} "“Megaten" (1 MI or greater) Tf all shots are listed, giving the dates ef the shots may perait accurate correlation of the shots with British debris samples and long range detection measurements. Also, if approximate yields of ail shote are furnished, by averaging these a fairly aceurste estimate of the total yield could be obtained. Since it may later be desirable to furnish the British the total flaaion yield of the REDWING series in connection with intelligence co- operation we believe it undesirable to give even approximete yields of all shote. With the changes noted above the Commission concurs in the use of the preposed talk for briefing the foreign observers at Operation REDWIEG. As revised we believe the briefing material does not contein any Restricted Tata and that a formal joint determination under Section lb ie oot required.
