Communicating by Morse code at night can be tricky. Even with precautions (as stated in the previous article), there are the risks of having your light signals detected. Furthermore, although it is obvious as to how the team in the field will communicate back to the main force, it is not obvious how the main force will send messages to the team in the field without alerting hostile forces or Zombies in the area as well.
In the diagram below, Bravo team is serving as a message relay team for the main force which is out of the line of sight of all hostile forces. Alpha is conducting reconnaissance of the river valley area.
For teams that have night vision capability, which includes night-shot equipped camcorders, the night becomes a surprisingly good time to communicate. Although invisible to the naked eye, infra-red light is visible to night vision equipment. Better yet, no real special device is needed to send the IR signals. A TV remote control works just fine.
Although one can argue that if anyone is using night vision in the area, it can be picked up, there are still some advantages:
– It’s still much less likely than getting picked up by the enemy who most certainly has eyeballs.
– Zombies can’t see it no matter what.
Preset Communication Times
It’s important to set a preset communication time. This would be the agreed upon time in which the team and the main force check in with each other to exchange any updates. To prevent detection, it is essential that “top of the hour” times such as 2200, and 0300 and “bottom of the hour” times such as 2230, and 0330 be avoided. The odds of the enemy scanning through their own night vision equipment at these hours are exponentially higher than at any other times.
