Gunmen

A man armed with a gun, especially a man skilled in the use of a gun.

When a cattle rancher or large landowner needs a personal or home security force, he will generally hire two, three or more men, adept in the use of small weapons. Traditionally they follow their employer everywhere. When they are at the ranch, they are easily spotted hangingaround the home, or on horseback checking out the property; they wear hats, blue jeans, dark glasses, long jackets or vests to hide a pistol.
When they enter a city, they often use private vehicles with tinted glass, keeping an eye on their boss from a prudent distance and with a low profile, individually or in groups of two. They are often called "hounds", in reference to their good hunting abilities. Their job is to "hunt" those who would harm their boss or his properties. Some cattle ranchers and large landowners hire them to protect their families as well.
