In the old Soviet Union, fighter pilots relied on GCI (Ground Control Intercept) stations to tell them where to turn and what targets to engage. Most soldiers in the Army were not taught to navigate so they could not function without senior leadership. By removing people's ability to make decisions, Communism kept people in control.
The inability of some of our school leaders to make rational decisions is baffling unless you suppose they're practicing their own brand of Communism.
The Russians and Chinese still use this dated system...
