The SPEAR System® (an acronym for Spontaneous Protection Enabling Accelerated Response) is a close-quarter protection system that uses a person's reflex action in threatening situations as a basis for defence.

[1] The founder, Tony Blauer, developed the SPEAR System® in Canada during the 1980s.

[2] The SPEAR System's origin began in 1982 with the developed "Panic Attack" drill that attempts to mirror the physiological response of a sudden ambush.

[3] In 2007 UK's Association of Chief Police Officers approved SPEAR for inclusion in the Personal Safety Training Manual for the British police.

[4][5] The Scottish Prison Service uses a modified version of SPEAR in its Personal Protective Techniques.
