ELI5: Explain Like I'm 5

Missing in action

Okay little one, sometimes when people are fighting in a war, they might get separated from their friends and family. When this happens, they are called Missing in Action or MIA for short. This means that we don't know where they are or if they are okay. Lots of people work really hard to try to find them and bring them back home safely. It's important to never give up hope, but also to remember and honor those who are still missing.
