There is a mystery surrounding those individuals who are trained to stealthy enter an area and take the shot. The military has elevated it to an art form. Police rely on it as a method of last resort to saves lives. This is a skill that is taught, but must be honed through constant practice. In the Airsoft community, MilSim players use this skill to take on opposing forces, and help them win the game.
Deploying trained snipers will affect the outcome. Finding this training is difficult, outside of the military or police. We have different programs designed for military, police, and MilSim'ers.
Due to the nature of these programs, government identification is required.
