> Directional laser beams are orders of magnitude to jam compared to radio wave. That alone makes it of big interest for military applications, even with 500 ms latency. I am reminded of RFC 1217 - Memo from the Consortium for Slow Commotion Research (CSCR) https://www.rfc-editor.org/rfc/rfc1217 https://www.rfc-editor.org/rfc/rfc1217 2. Jam-Resistant Land Mobile Communications This system uses a highly redundant optical communication technique to achieve ultra-low, ultra-robust transmission. The basic unit is the M1A1 tank. Each tank is labelled with the number 0 or 1 painted four feet high on the tank turret in yellow, day-glo luminescent paint. Several detection methods are under consideration:
