HEADQUARTERS, Joint Task Force SEVEN Washington 25, D. C. 10 November 1953 Annex K to CJTF SEVEN Operation Plan No, 3-53 HOSTILE ACTION ALERT PLAN Definitions: The following alert conditions are for use by the task force and should not be confused with CINCPAC alert conditions. Reports by ATCOM ENIWETOK to CINCPAC will conform with alert conditions as defined in Annex X and Z to CINCPAC General Emergency Operation Plan No, 11-53, dated 20 June 1953. WHITE Alert, as employed in this plan, indicates that hostile action or attack on forward area installations is imminent and will occur within a period of time specified by ATCOM ENIWETOK. RED Alert indicates that any one or all of the forward area positions are being subjected to hostile reconnaissance or attack. Since this plan is designed to comply with CINCPAC General Emer-~ gency Operation Plan No. 11-53, CJIF SEVEN will be referred to as ATCOM ENIWETOK. In the absence of CJTF SEVEN, while the task force headquarters is in the forward area, the senior task force officer present will discharge the responsibilities of ATCOM ENIWETOK. General Concept In the event of an outbreak of general war during the on-site operational phase, the task force will continue toward the execution of its mission within the capability of the forces remaining available unless instructions to the contrary are received from the AEC and DOD. The purpose of this hostile acticn alert plan is to insure that Operation CASTLE will be conducted with a minimum threat from direct hostile interference or threat of capture by enemy of its critical supplies, material and key scientific personnel. This plan establishes those measures best suited to the defense of the BIKINIENIWETOK area and will become effective upon commencement of the operational phase. The premise upon which this plan is based is that any actual attack by an enemy would, in all probability, occur when the entire task force has been established in the forward area. The objective would then more appropriately warrant and reward the risk involved. Short of such an actual attack, hostile action would in all likelihood be limited to missions of reconnaissance nature. ATCOM ENIWETOK will command and, through his staff, coordinate the defense when major elements of the task force are involved. The task force will be placed on WHITE and RED alerts in accordance with orders initiated by ATCOM ENIWETOK based on information secured from higher and adjacent commands or from local sources. When on a WHITE alert status, all task group commanders will prepare for RED alert conditions to the maximum extent possible in view of their primary tasks and missions. ATCOM ENIWETOK will suspend or modify existing security regulations regarding entry to islands north of ENIWETOK as required under the RED alert, The ground defense of the atolls is at all times a function of CTG 7.2. The existence of his trained, organized and equipped combat security force gives him a small but highly mobile striking force capable of rapid movement by vessel and/or aircraft to any threatened island in either of the atoll areas.
