Okay kiddo, so you know how sometimes there's a river or a big hole in the ground that gets in the way of soldiers trying to go somewhere or do something important? Well, a military bridge is like a really sturdy and strong kind of bridge that the soldiers can put up quickly to get over or across that obstacle.
It's kind of like when you play with your building blocks and you build a bridge, but the military bridge is much bigger and stronger. It can hold heavy trucks, tanks, and even people who are carrying heavy equipment.
Military bridges can be made out of different materials, like wood, metal or concrete, and they come in different sizes and shapes depending on the terrain and the vehicles that need to cross over.
They're really important because they help soldiers get to where they need to go quickly and safely. And sometimes they're the only way to get across a really big obstacle, like a river or a deep ravine. Thanks for asking, kiddo!
