MilSim, short for military simulation, offers players an immersive, highly realistic experience. A MilSim event usually lasts several days and simulates fictional scenarios with a realistic objective. The players wear uniforms in their faction's camouflage pattern and use airsoft replica weapons. MilSim offers a military experience with no actual engagement in a real conflict.

MilSim events tend to be fast-paced and action-loaded. However, players often have to wait for the story to develop. Either by standing watch, going on patrol, waiting to get assigned to a new mission by their commander, or waiting for the enemy to attack. This book shows the slower, quieter, and more intimate side of a MilSim event.
