There are many forms of reality self defense but this is a new era. Here are some definitions from Wikipedia:

Reality Based Self Defense (RBSD) is a blanket term for an approach to self-defense training that focuses on practical application. RBSD practitioners emphasize training that directly relates to the most dangerous of all possible situations. To accomplish this, training includes but is not limited to scenario and weapons (including guns, knives, and batons) training. In RBSD training prime importance is placed on gross motor skill training and simple, high-percentage moves. Furthermore RBSD schools minimize or eliminate elements of martial artstraining that are not directly related to practical application, such as acrobatic or aesthetic techniques, rituals, ceremony and kata. In their techniques, many RBSD systems draw on military systems, especially World War II combatives.

RBSD practitioners believe that overall efficiency and effectiveness for the average person will override any consideration of style, and that priority should be given to those tactics which allow the unarmed individual to safely and efficiently arm themselves as quickly as possible during a confrontation. This is considered a much higher-percentage solution than attempting to prevail by virtue of one’s unarmed skill and training.

Gross motor skills are simple, large-muscle group actions like squats, push-ups and push/pull-type movements. This includes basic fighting skills like a straight punch, a hook punch or a Thai boxer’s knee strike for example. Unlike fine and complex motor skills, gross motor skills do not deteriorate under stress;^{[citation needed]} in fact, they may be enhanced by the effects of fear and stress.^[1]
