So you know how soldiers have to move around a lot to do their job and get to where they need to be? Well, sometimes they use bicycles to do that. The Army Cyclist Corps is a group of soldiers in the army who use bicycles instead of cars or trucks to move around.
Bicycles are very useful because they don't make noise and don't use any gas, so soldiers using bikes can move around more quietly and without having to stop and refuel. They can also move more quickly in certain situations, like if they need to go through rough terrain or narrow paths where larger vehicles can't go.
Soldiers in the Army Cyclist Corps have special training to learn how to ride their bikes really well, even on rough terrain. They also carry all their gear and weapons on their bikes, which can be a lot of weight, so they have to be very strong and skilled.
Overall, the Army Cyclist Corps is a way for soldiers to move around quickly, quietly, and without using a lot of resources, which can be very helpful in certain situations.
