Armed security guards are trained to use deadly force if necessary and usually carry a firearm. They are typically required to complete specialized training and obtain the necessary licenses or permits to carry a firearm. On the other hand, unarmed security guards do not carry a firearm and often use non-lethal weapons like batons, pepper spray, or tasers. They are trained to respond to situations without the use of force, relying on deterrence and de-escalation techniques.

Security guards are required to complete a variety of training courses, including a pre-assignment class, which covers topics such as security procedures, communication, and report-writing. They may also need to complete additional training, such as first aid, CPR, and AED, as well as active shooter threat response and self-defense courses. In some cases, guards may also need to obtain a security guard license or complete a specific number of hours of training before they can work in the field.
