SECTION I. BASIC THREATCON PROCEDURES
1. General.The threat conditions (THREATCONs) outlined below describe the progressive level of a terrorist threat to all US military facilities and personnel under DOD Directive O-2000.12. As approved by the Chairman of the Joint Chiefs of Staff, the terminology and definitions are recommended security measures designed to ease inter-Service coordination and support of US military antiterrorism activities. The purpose of the THREATCON system is accessibility to, and easy dissemination of, appropriate information. The declaration, reduction, and cancellation of THREATCONs remain the exclusive responsibility of the commanders specified in the order. Although there is no direct correlation between threat information (e.g., Intelligence Summaries, Warning Reports, and Spot Reports) and THREATCONs, such information, coupled with the guidance provided below, assists commanders in making prudent THREATCON declarations. THREATCONs may also be suffixed with the geographic area deemed at risk. Once a THREATCON is declared, the selected security measures are implemented immediately. NOTE: When used in antiterrorism plans, recommend that the information contained in this appendix be marked "For Official Use Only" (FOUO) in accordance with DOD Regulation 5400.7-R, October 1990. The DOD Directive O-2000.12 recommended measures are:
(1) Measure 1. At regular intervals, remind all personnel and dependents to be suspicious and inquisitive about strangers, particularly those carrying suitcases or other containers. Watch for unidentified vehicles on or in the vicinity of US installations. Watch for abandoned parcels or suitcases and any unusual activity.
(2) Measure 2. The duty officer or personnel with access to building plans as well as the plans for area evacuations must be available at all times. Key personnel should be able to seal off an area immediately. Key personnel required to implement security plans should be on-call and readily available.

SECTION II. SHIPBOARD TERRORIST THREAT CONDITIONS
2. Shipboard Terrorist THREATCON Measures.The measures outlined below are for use aboard vessels and serve two purposes. First, the crew is alerted, additional watches are created, and there is greater security. Second, these measures display the ship's resolve to prepare for and counter the terrorist threat. These actions will convey to anyone observing the ship's activities that the ship is prepared, the ship is an undesirable target, and the terrorist(s) should look elsewhere for a vulnerable target. The measures outlined below do not account for local conditions and regulations or current threat intelligence. The ship's command must maintain flexibility. As threat conditions change, the ship's crew must be prepared to take actions to counter the threat. When necessary, additional measures must be taken immediately. The simple solution to THREATCON CHARLIE or DELTA is to get under way, but this option may not always be available.
