"Mail Call" is a term used to describe the process of delivering mail to individuals or groups, often in a military context. During this time, soldiers receive letters, packages, and other correspondence from family and friends, which can boost morale and provide a connection to home. In military settings, Mail Call is typically a scheduled event where a designated officer or non-commissioned officer distributes the mail. This practice helps maintain communication between service members and their loved ones, reinforcing emotional support during deployments or training exercises.
