In the ROC, before 26 May 1995, military training lessons were mandatory to all students of senior high schools, colleges and universities. As a result, there were and still are many military instructors stationed at every school more advanced than senior high schools. Naturally these military instructors are also commissioned officers in active duty either dispatched from or trained by the branch of Political Warfare. Before 1995, one of their missions at school is to closely watch, report, or even suppress any possible anti-government or political activity launched by students on or off campus.
