Troops are groups of soldiers organized for military operations. They can vary in size, from small units like squads to larger formations such as battalions or brigades. Troops are trained to perform specific tasks, including combat, peacekeeping, and humanitarian missions. In many countries, troops are part of the armed forces, which may include branches like the Army, Navy, and Air Force. Troops can be deployed domestically or internationally, often working alongside other military units or allied forces to achieve strategic objectives.
