My comment, as well as the parent post, refers to training. When not in training, the placement of armament switches, as well as many other risk avoidance measures, will vary based on the type of conflict and risk. There is a good article from a Ukrainian fighter pilot you can read to see the extreme opposite of the training environment (high risk flight with enemy overhead). The most surprising thing is that he doesn't run pre-flight checks. I bet he took off with those switches armed.
