Commandos are a group of special soldiers from the United Kingdom who have special training to do very difficult military missions. They are a bit like superheroes because they can do things that other soldiers can't do.
The commandos are trained to be really good at different things like climbing high mountains, working under the water, and moving quietly and quickly without being seen. They are also very strong and can carry heavy things for long periods of time.
When there is a mission that needs to be done that is too dangerous or important for regular soldiers, the commandos are called in to do it. This could involve sneaking behind enemy lines, rescuing hostages or even attacking enemy bases.
To become a commando, soldiers have to go through very tough and long training that tests their physical and mental strength. They have to learn things like how to survive in the wilderness, how to shoot guns accurately and how to work together with other commandos.
So in summary, commandos are special soldiers from the UK who have special training to do really difficult military missions. They are like superheroes because they can do things that other soldiers can't do!
