Begin to attrit the enemy at the maximum effective range of your weapons.
That was one of the most important things I learned as a young Infantry Lieutenant during the Cold War. We would have almost certainly been facing Soviet forces larger than our own. We had to wear them down as they closed with us in order to destroy them before they could reach us. This is every bit as true today in the context of personal protection.
“Don’t fire until you see the whites of their eyes” is a famous saying from the Battle of Bunker Hill during the Revolutionary War. Very few people understand that ‘the whites of their eyes’ basically represented the maximum effective range of the smoothbore musket. That’s the underlying concept of the order.
No matter what our weapons are, we need to understand their maximum effective range. Maximum effective range is sometimes limited by the weapon, as in the case of the smoothbore musket or pepper spray. In other cases, it is limited by the capability of the user. The firearms instructors and SWAT team members of the Los Angeles Police Department are capable of using their weapons at a greater distance than the average patrol officer. That’s not a slam on the patrol officers, rather it is a result of training, practice, and experience.
In order to know the maximum effective range of your weapons, you have to understand them and test them. This testing and understanding is a key component of John Boyd’s Aerial Attack Study. An integral part of ‘Orient’ is knowledge of the capabilities (Previous Experience) of your weapons.
Keep in mind that ‘line in the sand’ is both a chronological concept as well as a geographic point. If a situation goes on for a while, it’s time to put an end to it, one way or another.
