​It’s important to understand that while physical fitness movements (push-ups, sit-ups) and running times can be good measures of physical output, they are not direct indicators of tactical performance but rather of one’s level of general physical preparation. Physical preparation is the operator’s overall level of conditioning in strength, speed, endurance, and other basic factors of fitness. It is the degree to which we can measure efficient function of the whole human organism, the ability of all the body’s systems to recognize and adapt to a multitude of stressors appropriately.   

 

It's your level of being in shape to realistically perform your occupational duties - that you can move your body into the positions you need to, and in those positions you can physically handle the speeds, forces, and durations of those activities to successfully complete the tasks.

 

Again, it is not tactics, it is the body’s ability to handle the physical demands of executing the tactics at an optimal level. ​​​​​​​​​​​​​​​​​To some degree every tactic involves multiple physical outputs, and a deficiency in one or more of these outputs (mobility, aerobic development, upper body strength, agility/balance, etc) affects the ability to perform them optimally.
