The CSM must consult with the S2 to determine the threat and establish security that will meet that threat. Communications with higher headquarters must never be lost. The advanced party must establish communications with higher headquarters prior to the TOC breaking down and moving. Ensure that coordination and communications with adjacent units are established if the adjacent unit is within range of the battalion's direct fire weapons systems. The S2 develops NAIs, and the S3 develops a plan to keep the NAIs under observation.
Submit sector sketches.
Companies submit sector sketches to the battalion for incorporation into the battalion security plan. Battalion aircraft should arrive after the ground portion of the main body. During AA movement, the battalion must consider and make provisions for maintaining communications with the battalion aircraft located at the previous AA site. When the aircraft arrive they should be positioned in a predetermined location selected by the advanced party. The location of the aircraft should provide the maximum concealment possible.
