Actually I have a question and it relates to Strategic Defence globally rather than just China.
All Nuclear Forces drill and drill regularly, the drills test the procedures (drill) and the equipment systems etc. When the drills are undertaken, I understand that the participants are informed early on, that it is only a drill and so have no issues with completing the procedures and simulating a weapons launch.
I am also aware, that in popular fiction, that when the order is real, there is often pyschological issues with actually launching the weapons.
My question is this. Do strategic forces ever tell the participants that a drill is not an exercise but the real thing, in order to test the psychological response of the soldiers?
The defence "Befehl ist Befehl" was not accepted in Nuremberg.Maybe they drill you again and again under timed circumstances, and they never tell you in each case whether it is the real one or not.
And then the day you retire/reassigned you got out of the bunker and you see that the sky is still blue and you say a prayer.
In other words it is not your job to ponder if an order is a valid one, your job is just to execute them, and trust that the higher ups will not screw things up. Things like this happens a lot in real life - like when you trust your banks not to screw with your money that you've deposited with them.
