D-56: Security Element

Previous: D-53: Civil Authority Assistance

D-56. The nature of the checkpoint makes it particularly vulnerable to enemy attack. Protection should be provided for overall position as well as those of subordinate positions. Concealed sentries should also be positioned on the approaches to the checkpoint to observe and report approaching traffic, and to prevent persons or vehicles from evading the checkpoint. When available, early warning devices or radar may be used to aid guards on the approaches to the checkpoint.

D-57. The security element stays alert for changes of scenery around the checkpoint. Crowds gathering for no apparent reason or media representatives waiting for an event are all indicators something may happen.
