I do have to give the guards points here in that in both cases, they had their jammer ready, noticed the drone in time -- it has got to be mind-numbingly boring just standing around a fuel tank or in the second case, what I assume is an electrical transformer, all day waiting to see if maybe a drone will show up. And you have to act within a couple of seconds. I'd have been expecting to see more video of people screwing around on their phone and smoking or something.
The jammer they were supplied with didn't work, but the human side actually did work. I'd have expected the reverse to be more-likely -- the jammer to work had it actually been used, but for the guards to be off screwing around.
EDIT: Well, Electrical Transformer Guard Dude might have been notified that there was a drone coming in by Russian air defense or something, because he was on his phone and looking around prior to it showing up, so guess maybe it wasn't just him being on-the-ball.
