The training ground is a spatial carrier for conducting military training. Modern warfare increasingly demands the ability of troops to engage in joint operations. To bring different branches of the military together and fight, the first step is to gather them together for training. In this sense, the training ground is not only a "sharpening stone" for the military to carry out routine training, but also a "sharpening pool" for forging joint combat capabilities. It must provide the most basic spatial conditions for various branches of the military to carry out joint training and research. Whether it is a certain army brigade opening its own camp to welcome neighboring troops, or an air force aviation brigade and an air defense unit of the army stationed on the same site for training, they are reshaping the function of the training ground with a systematic thinking approach. This not only improves the efficiency of training resource utilization, but also provides a smooth communication channel for the deep integration of various military branches. When army helicopters and navy speedboats fight in the same sea area, and when air force fighter jets and army air defense firepower are pointed at the same sky, the training ground has moved beyond its traditional functional positioning and become a "testing ground" for different branches of the military to optimize combat links and refine tactical tactics, effectively accelerating the generation of joint combat capabilities among troops. Transforming the training ground from an "exclusive territory" to a "shared platform", all levels should break down thinking barriers, establish scientific and efficient open mechanisms, strive to upgrade single service venues into joint experimental venues, promote system integration through venue sharing, achieve mutual benefit through resource sharing, and strive to hone winning tactics on the battlefield.
