The last resort
- Type
- Nuclear device
- Activation
- Codes from two officers
- Location
- Cheyenne Mountain

A nuclear charge hidden under the base. If the enemy takes the SGC, it destroys the Gate and seals the mountain to save Earth.
Overview
The countdown can only start with senior officers' codes, and can be stopped until the last second. It is designed for an invasion through the Gate.
Worth knowing
The series triggers it several times, often against intruders who came through the Gate. Each time, the countdown echoing in the corridors cranks up the tension.
