Officer ranks refer to the hierarchical structure within military and law enforcement organizations. These ranks help establish authority, responsibility, and command within the force. Common officer ranks include Lieutenant, Captain, and Major, each with specific duties and levels of leadership. In the military, officer ranks are typically divided into two categories: Commissioned Officers and Non-Commissioned Officers. Commissioned officers, like Colonels and Generals, are appointed and hold higher authority, while non-commissioned officers, such as Sergeants, provide essential support and leadership at lower levels. This structure ensures effective management and organization within the ranks.
