Optimize the army

This version of the civilized army is too stupid. Elves attack human villages. The army of one village has completely destroyed the human army of another village. Instead, they are waiting for the army of Elves to slaughter the village.
Also, when civilized races attack each other, the small captains of the army and the fallen soldiers will retreat, which is not as ornamental as the previous version of the war.
I think that after the leader of the village army was killed, his army killed the enemy for revenge instead of retreating to the village and regrouping a new leader.
There are also some village leaders who will slow down when the empire goes to war with the enemy or retreat in a hurry when they arrive at the enemy's border, which makes this version of the war unattractive.
I hope the game production team can optimize this civilized military mechanism. If the military mechanism is optimized in place, I personally think this game will be perfect.
