In traditional war novels, the protagonist leads troops to fight. This idea turns the "command" ability into an "ultimate immersive intelligence system." The protagonist did not travel through time, but was stimulated by an unexpected encounter with an electromagnetic pulse and a flash flood. His brain potential was stimulated, and he became quantum entangled with an ancient war game (possibly a deduction board from the Three Kingdoms period). He cannot directly improve the combat effectiveness of his troops, nor can he create weapons out of thin air, but he can use this sandbox as a "God's perspective battlefield radar" to accurately identify every weak point in the enemy's defense line, every troop transport channel, and even "hear" the enemy commander's curse words in the camp.
