Simulation exercises for confrontation are a compulsory course for modern military commanders. A commander who can't conduct simulations might not even obtain a graduation certificate, let alone become a victor on the battlefield.
No matter how genius his tactics and operational plans may be, without simulation as a foundation, they are nothing more than empty fantasies. A plan without the support of simulations requires risking soldiers' lives to validate it, at the cost of blood.
Even if the Staff Department is responsible for simulations, not all operational plans can be handed over to them. Some plans have confidentiality levels that are restricted to the commander himself.
Moreover, if a commander, as the command core, cannot learn and scrutinize his own plans through the simulation process, it means he could get lost in the ever-changing fog of the battlefield at any moment.
