There are a lot of video calls in my story, being that it deals with upper-level command structures at different bases, and yet I can't find much online as to the protocol for how video calls are handled. When a subordinate is on a video call with a superior, they are both speaking to and seeing each other, so really the technology interface is the only difference from a face-to-face encounter, right? So, does the subordinate then also salute the superior during said video call? Or would that be unnecessary due to the technological separation? It feels weird to imagine someone saluting toward a computer, but I'll write it that way if that's how it's done. Does anybody know?
