DarkDot PACE
Primary, Alternate, Contingency, Emergency
A communication planning methodology that establishes a hierarchical sequence of communication means, ensuring command and control is maintained when primary systems fail.
Every unit and element must have a PACE plan before an operation. The plan assigns a specific communication method to each tier and defines the triggers for switching to the next tier down.
The Four Tiers
| Tier | Typical Method | Trigger to Switch |
|---|---|---|
| Primary | Main tactical radio net (e.g., FM radio) | Radio fails or is compromised |
| Alternate | Secondary radio net or different frequency | Alternate fails |
| Contingency | Satellite comms, relay, or runner | Contingency fails |
| Emergency | Pre-arranged signals, flares, messenger | All others unavailable |
Writing a PACE Plan
A PACE plan must specify: method, frequency/channel, call signs, and authentication table reference from the SOI. It is briefed during the OPORD (Paragraph 5: Command and Signal) and rehearsed before movement.
Key Principle
Units do not wait until communication breaks down to switch tiers — they monitor for degraded performance and switch proactively. The PACE plan is only effective if every element knows it by heart.
