ELI5: Explain Like I'm 5

Military parade

A military parade is like when you have a special day at school and you dress up nice to show off to your teachers, parents, and friends. The military does the same thing, but instead of dressing up in fancy clothes, they wear their special uniforms and march in a straight line to show off how strong and organized they are. They also have big trucks and tanks that they drive around to show all the cool machines they use to protect our country. It's like a really big party for the military to celebrate how great they are and make everyone feel proud of them.
