The United States Civil Disturbance Plan 55-2.
If any civil disturbance by a resistance group,
religious organization, or other persons considered to
be non-conformist takes place, under Appendix 3 to
Annex B of Plan 55-2 hereby gives all Federal forces
total power over the situation if local and state
authorities cannot put down said dissenters.
Annex A, section B of Operation Garden Plot defines tax
protesters, militia groups, religious cults, and
general anti-government dissenters as Disruptive
Elements. This calls for the deadly force to be used
against any extremist or dissident perpetrating any and
all forms of civil disorder. Under section D, a
Presidential Executive Order will authorize and direct
the Secretary of Defense to use the Armed Forces of the
United States to restore order.
