I was at a military site and in the safety/security training and warned of horse play. They told the story of a helicopter going along a dirt road. Some of the manual laborers riding in the back of the large open truck pointed their shovel handles at the helicopter.
A short while later the truck came over a rise and came face to face with two Humvees blocking the road with a bunch of guns pointed at them. And an armed helicopter hovering over the road with its guns pointed at them.
I don’t think that the group was arrested, but the entire company doing the work was kicked off the site.
I would often do work just outside a very secure area fence and alone. Still on the site and within a gated area - but out in the dirt and sage brush. Always made sure I was wearing my high-vis vest, truck with cones sitting on top of it to let them know I wasn’t hiding anything.
Still a bit disconcerting when the two guys come driving up, come out of their truck with their rifles at the ready and ask to see my badge and what am I doing.
35 years ago my dad won a contract to do work at the local military base where construction was going on. the equipment needed to be moniterd 24 hours but no real work to do so my dad had me there at night because the contract called for the monitoring. I was visited 4 times that night by base security and each time told don’t leave the immediate vicinity because it being at night I might be shot before security realized I was just a 15 year old kid who out of boredom decided to wander....I stayed in the truck and only left to do the minimal work that was needed....the site was a nuclear silo and the men were deadly serious about the fact that if I left the area I was in I might be shot.
