$FISN Pete Hegseth rolled out project Fortress America yesterday. Says every US military base will have its own power supply in case electrical grid goes down with cyberattack or other terrorist plots. Most likely this will be nuclear. Would make the most sense too if it was underground in case of bombing or drone attacks. Huge market it they can deliver. https://www.thestatesman.com/world/what-is-fortress-america-us-plan-to-keep-military-bases-running-through-cyberattacks-and-sabotage-1503645382.html

$FISN Not to worry, this is why you hire a Chief People Officer when you only have 60 employees: probably to spell check the press releases refuting the short sellers. Useful.
