Which method is typically NOT included under empty hand techniques?

Empty hand techniques are primarily focused on controlling or subduing an individual without the use of weapons. In this context, joint manipulation, pressure point control, and containment techniques all focus on utilizing physical skills and body mechanics to gain control over a suspect or individual.

The use of firearms is distinctly different from these techniques because it involves a weapon that can cause lethal force. Firearms training and the use of weapons occupy a separate category of law enforcement tactics that emphasizes both lethal and non-lethal approaches but does not qualify as an "empty hand" technique. Therefore, firearms, which rely on equipment rather than physical control methods, are correctly identified as not being part of the empty hand techniques utilized in training for self-defense or suspect control.
