You're two klicks into a movement when your radio dies. No warning — just static. Your team is spread out, terrain is thick, and you still have 45 minutes to the objective. What do you do? Here's the framework I teach: 1. **Stop.** Don't panic-move. Get behind cover and assess. 2. **Visual signals.** Hand-and-arm, mirror, or pre-arranged light signals. 3. **Rally point.** Fall back to the last designated rally if you can't re-establish comms within 60 seconds. 4. **Dead reckoning.** If you're the lead, push to the objective on schedule. If you're trailing, hold at the rally. The team that drills comms failure survives it. The team that doesn't, fragments. What's your go-to backup when the radio goes silent?
