Security patches complete an official, professional look for uniformed security guards. Security officer patches may include embroidered hat patches and shoulder patches bearing a security emblem. Guards may also wear security patches on the backs of their jackets.
Security guards may be contracted through security firms, or they may be in-house security officers. Either way, there are security guards everywhere--banks, amusement parks, malls, jewelry stores, gated communities, casinos, armored trucks--and they all need to be outfitted with security officer patches. There are general security emblems, but private security companies often have their own security emblem that indicates affiliation with the firm.
