And how do you do the opposite? How do you use a script to place an army without a hero on the map? In the sense that a monster is standing there, a player kills it, and after a while, the script places another monster in that spot. I hope I explained it clearly? Just please explain in as much detail as possible, as I am a beginner.

You can't do that with an army – if it's destroyed, all the scripts associated with it will be lost as well. The only thing I can suggest is to place a garrison and configure it so that after a certain number of days after it's captured, it's transferred to a neutral player and an army is added to it. I'm too lazy to explain how to do this, so I'll just post a map with an example – it has a garrison that becomes neutral exactly one week after it's captured by the red player, and one air elemental is added to it. You can place a different army or change the respawn period by replacing the seven in the appropriate window with a different number.
