TACTICS. An enemy's interactions are always serve DUAL PURPOSES, achieving military objections in economics, trade, political, electoral interference, diplomatic, propaganda, criminal, sabotage, fake news, espionage, cyberwarfare, legal warfare, and guerrilla warfare. It can include limited direct shooting warfare, but normally uses proxy wars ('shooting' or 'hot' wars) waged by surrogates, sub-contractors, and allies.

DOMESTIC NETWORKS - CREATING RELATIONSHIPS, ALLIANCES. 
During a Cold War era, enemies purposely develop relationships and networks that can later be used for domestic spying, sabotage, and guerrilla warfare during a time of war. These networks are used for intelligence gathering, subversive activities, and corruption of leaders and strategic institutions.

DOMESTIC MILITANTS.  This is done by starting, partnering with, funding, aiding the growth of, and utilizing Domestic Militant Allies like:

• IDEALOGICAL and POLITICAL GROUPS - used to ferment/stir-up domestic unrest and violence;

• CRIMINAL GANGS and CARTELS - used at all levels, for sabotage, destroying lives, the subversion, destruction, and corruption of strategic industries, business, and military assets and personnel.

FROM COLD WAR to HOT WAR: GUERILLA WARFARE ON U.S. SOIL.  
During a Cold War Era, these militant groups have been, knowingly or unknowingly, equipped and developed for a 'hot' shooting war, where they will be used in Guerrilla Warfare and Sabotage on U.S. Soil.  Are all 'groomed' people in domestic militant groups participate? That's an unknown, but what is known: some will.

FOREIGN MILITANTS.  This is done through the physical infiltration onto U.S. Soil and integration into U.S. Society of Active and In-Active (sleeper) Spies and Soldiers. They are used for active operations and preparation for guerrilla warfare and sabotage in a hot war.

HISTORY. Cold War Tactics have their roots in the US-Soviet Cold War (1947-91) and in World War 2 (1939-45). In WW2 they were used in enemy occupied lands by the U.S. and Britain (Allies) with domestic 'resistance groups' who fought against NAZI Germany and Fascist Italy (Axis). These tactics expanded greatly in number, types, and use during 1947 to 1991 during the global US-Soviet Cold War.
