Although it is October, the late night in southern Guangdong is still not cool. In the jungle of a comprehensive training base in the suburb of Yangcheng, a comprehensive and coherent examination of orienteering cross-country courses is about to begin in the dark. "The night examination is chosen to simulate the real battle scene. The students will face unfamiliar environment, complex routes and bad weather. This is a test of your physical strength, tactics and teamwork spirit. I hope that the students can flexibly use the knowledge learned in the class, carry forward the special forces spirit of challenging the limits and never giving up, and successfully complete the examination task." Professor Jiang Chuang, the leader of the assessment team, encouraged the students after announcing the summary of work. The students with guns were energetic, confident and eager on the young faces covered with camouflage. After receiving the task card, these future special forces commanders disappeared in the vast dark forest with the standard special operations team infiltration formation. The Army Special Operations Academy has been organizing such a comprehensive and coherent assessment of orienteering for four consecutive years. This time, the teaching team set up a comprehensive curriculum of infiltration, guidance, shooting, team tactics, etc., and for the first time set the assessment time at midnight. A total of 23 points have been set up on the distance of nearly 9 kilometers, interspersed with 13 sub course assessments, which is an all-round test of students' physical ability, skills, knowledge, team awareness, tactical literacy and will quality. Four years ago, when planning the course, the teaching team did not regard orienteering as a simple extension of the course "marching according to the map" in the military topography course, but based on the actual requirements of special operations for commanders under the future information conditions, created a set of characteristic course system integrating "improvement, expansion and breakthrough" for students at different levels. Terrain is one of the important research objects of orienteering course. Only in the terrain with wide coverage, many samples and all elements involved, can participants develop real skills. The college has changed the practice of "familiar with the terrain and going round and round, fixed the process", transferred the classroom from the college playground to a strange area, and used the surrounding forests, rivers, mountains, lakes and other different types of terrain to draw the students to various possible combat scenes to fight and train strictly. It not only effectively improves the adaptability of the trainees to the whole area combat, but also accumulates rich experience and a large amount of data to adapt to different terrain, laying a solid foundation for the trainees to shorten the distance from the playground to the battlefield. Before each class, the instructor will ask the trainees to wear all the combat equipment, and take the threat of the enemy as an element throughout the whole teaching process, so as to add a combat element to the teaching. The final examination of each semester is also full of strong fighting flavor. In the past few years, after studying a large number of actual combat cases of Chinese and foreign special forces, the teaching team organically integrated the classic special combat cases with the assessment, selected the terrain, landform, vegetation, soil, water system and other environments similar to the combat cases, used sound, light, electricity, magnetism, explosion and other technologies to create a combat scene, and comprehensively tested and inspected the comprehensive application level of students' physical skills. "Drop!" About 4 hours later, Li Chao, a 2020 student, took the lead in crossing the finish line. The excellent examination results come from the hard training at ordinary times, and Li Chao's requirements for himself
