Guards are individuals responsible for maintaining safety and security in various settings, such as buildings, events, or public spaces. They monitor activities, check for unauthorized access, and respond to emergencies. Guards can work in different environments, including malls, schools, and concerts. There are different types of guards, including security guards, bouncers, and military guards. Each type has specific duties and training requirements. Security guards often patrol areas, while bouncers manage crowd control at venues. Military guards protect sensitive locations, such as military bases or government buildings.
