With the promulgation of the Patriotic Education Law, the popularity of national defense education has gradually increased. Jiangsu, Shandong, Zhejiang and other provinces have successively adopted documents related to patriotism education to bring national defense education into the classroom and enhance patriotism. Common national defense education and training subjects include: laser simulated target shooting training, real CS red-blue confrontation training, 92/95 simulated dismantling explanation, mortar shooting, simulated mine clearance, simulated Grenade throwing and so on. The venue is large enough, and you can also consider making a small arms exhibition hall to explain the history of firearms. The training subjects and contents are very rich.
