Explanation
An officer is someone who works for a police force or has a high position in the military. Police officers in some towns and cities patrol on bikes, or occasionally even on horseback. You might see police officers patrolling in your neighborhood, or guarding a bank, or inspecting bags in a train station. Military officers hold a high rank, and they issue commands to lower-ranking service members, and an officer is also the commander of a military ship. Another kind of officer is simply "a person who holds an office," which can mean an elected position or a senior job at a company, like a "chief executive officer," or CEO.
