Mine hunting is an important way to counter intelligent fuze mines，but its efficiency is low due to factors such as battlefield environment，mine conditions，equipment failures，and equipment utilization. The mine hunting sergeant is the first person in charge of mine countermeasures equipment. Thus，enhancing the core competency of mine hunting sergeants is of great significance for mine countermeasures. This article focuses on the practical needs of training mine hunting sergeants in colleges and universities. Firstly，the core competency of mine hunting sergeants is elaborated. Then，the special situation of mine hunting is analyzed from several aspects such as special environment， potential opponents，special equipment performance，and special faults. Based on this，a training method for special situation reconstruction based on simulation technology and mine hunting in actual water area is proposed.
