ELI5: Explain Like I'm 5

Fog of war

Okay kiddo, imagine you and your friends are playing hide and seek in a big park with many trees and bushes. You already know the park very well because you came there many times before. But this time your mom blindfolded you and spin you around many times before letting you go hide.

Now, you can't see anything around you, everything is dark and confusing. You don't know where your friends are, and you have to guess where they might be hiding. You might bump into trees or fall over obstacles that you didn't see. This is called a "fog of war".

When armies fight, they sometimes don't know where their enemy is or what they are doing. They have to guess and make decisions based on incomplete information. This is also called "fog of war."

In war, there is usually a lot at stake, and people can lose their lives. So, it's important to make decisions based on the best information available. But, you can never be sure if your information is correct or if you have all the information you need.

This is why armies send out scouts or use drones to try to gather information about what the enemy is doing. They also use things like maps, radio communication, and surveillance cameras to see what's happening on the other side.

But, even with all this information, there is often still a lot of uncertainty and confusion. This is why wars are so unpredictable and dangerous.

So, in short, "fog of war" means not knowing what's going on in a battle, just like when you can't see in a game of hide and seek. It can be dangerous and unpredictable, which is why it's important to gather as much information as possible to make the best decisions.
