Military
New people in the military are often called “recruits”. They have training at a special camp, sometimes called “boot camp" or "basic training". During this training, the recruits usually have very little free time. They learn to understand the "orders" or "commands" that are given by the officers to the "troops". (The troops are the military people in a group.) They learn the right ways to obey the orders. They do a lot of exercise to improve their fitness and strength. They learn about weapons, first aid, and their uniforms and "kit" (their equipment). Recruits also learn how to march. (This is the way to walk together, keeping "in step".) Learning to march is sometimes called “drill”. By the time soldiers finish "boot camp", they should know enough to be a helpful person in their group. The camp usually finishes with a parade in which the newly trained recruits show off their marching and other skills they have learned in front of important visitors. Once the recruits are fully trained, they are ready to defend (protect) their country from attack, or to go to war if necessary.
