Training of signalmen (soldiers and officers).
Teach cadets to mount connectors on a cable. N type, PL, sma, BNC, TNC Under crimping and under assembly.
Without these skills, there is no way in the army. So that each cadet personally collected a dozen connectors.
In one building, I meet the signalmen of the Armed Forces. There is a repeater antenna on the elevator shaft, and a repeater is located 4 meters away in the elevator room. And between them … 100 m cable bay.
I say: you can’t do that. They answer: we understand, but there is a soldered N connector on both sides, and no one here knows how to unsolder it.
