As part of the EU research project called "Interdisciplinary Education and Training on Hybrid Warfare", the Armed Forces Academy of Gen M.R. Štefánik organises the second event in a row called "Learning, Teaching, Training Event 2". This event will conclude the two-year development of a comprehensive training course on hybrid threats. The massive open online hybrid warfare course is one of the most important outputs. It will be a course available to the general public, the structure of which enables the implementation of a separate teaching block/course on hybrid threats. It will be used at several universities, not only within the EU. It is in Liptovský Mikuláš that the functionality of the individual modules of this online course will be tested in the form of lectures, seminars, exercises and tests. The activity will last a week from January 29 to February 2, 2024, and in addition to Slovak and foreign lecturers, 55 students from Italy, Romania, Hungary, Israel, and Slovakia will participate. The last two days are intended for knowledge verification as a computer-assisted exercise (CAX) at the AOS Simulation Centre.
