The Black Liberation Army (BLA) was an underground, black nationalist militant organization that operated in the United States from 1970 to 1981.
 Composed largely of former Black Panthers (BPP), the organization's program was one of armed struggle against the United States Government, and its stated goal was to "take up arms for the liberation and self-determination of black people in the United States."
 The BLA carried out a series of bombings, killings of police officers and drug dealers, robberies (which participants termed "expropriations"), and prison breaks.
Marilyn Jean Buck (December 13, 1947 – August 3, 2010) was an American Marxist revolutionary, and feminist poet, who was imprisoned for her participation in the 1979 prison escape of Assata Shakur, the 1981 Brink's robbery and the 1983 U.S. Senate bombing.
 Buck received an 80-year sentence, which she served in federal prison, from where she published numerous articles and other texts.
 She was released on July 15, 2010, less than a month before her death at age 62 from cancer.
The Brink's robbery of 1981 was an armed robbery and three related murders committed on October 20, 1981, which were carried out by six Black Liberation Army members: Jeral Wayne Williams (Mutulu Shakur), Donald Weems (Kuwasi Balagoon), Samuel Brown (Solomon Bouines), Samuel Smith, Edward Joseph, and Cecilio "Chui" Ferguson; and four former members of the Weather Underground, now belonging to the May 19th Communist Organization, consisting of David Gilbert, Judith Alice Clark, Kathy Boudin, and Marilyn Buck.
Ashanti Alston Omowali is an anarchist activist, speaker, and writer, and former member of the Black Panther Party.
 Even though the party no longer exists, Alston sometimes refers to himself as a Black Panther, and sometimes as "the @narchist Panther", a term he coined in his "@narchist Panther Zine" series.
 He was also member of the Black Liberation Army, and spent more than a decade in prison after police captured him and he was convicted of armed robbery.
 Alston disputes the moral issues of property and terms his activity in the BLA "bank expropriation".
 Alston is the former northeast coordinator for Critical Resistance, a current co-chair of the National Jericho Movement (to free U.S. political prisoners), a member of pro-Zapatista people-of-color U.S.-based Estación Libre, and is on the board of the Institute for Anarchist Studies.
 Since 1999, Alston has produced four issues of the zine, "@narchist Panther Zine" (the name being a reference to his current affiliation as an anarchist, and his past membership in the Black Panther Party).
 Alston has identified himself as a black anarchist as well as a postmodern anarchist.
Assata Olugbala Shakur (born JoAnne Deborah Byron; July 16, 1947, often referred to by her married surname Chesimard), is a former member of the Black Liberation Army, a black nationalist urban guerrilla group, who was convicted in 1977 of the first-degree murder, under New Jersey's "aiding and abetting" statute, of State Trooper Werner Foerster during a shootout on the New Jersey Turnpike in 1973.
 She escaped from prison in 1979 and fled to Cuba, where she was granted political asylum.
Kuwasi Balagoon (December 22, 1946 – December 13, 1986), born Donald Weems, was a Black Panther, a member of the Black Liberation Army, a New Afrikan anarchist, and a defendant in the Panther 21 case in the late 1960s.
 Captured and convicted of various crimes, he spent most of the 1970s in prison.
 Balagoon escaped from prison several times, going underground and resuming BLA activity.
 He was finally captured and charged with participating in an armored truck armed robbery, known as the Brinks robbery (1981), in West Nyack, New York, on October 20, 1981, an action in which two police officers, Waverly Brown and Edward O'Grady, and a money courier (Peter Paige) were killed.
 Convicted of murder and other charges and sentenced to life imprisonment, he died in prison of pneumocystis pneumonia, an AIDS-related illness, on December 13, 1986, aged 39.
 Balagoon was bisexual.
The People's Liberation Army Navy (PLAN; ), also known as the PLA Navy, is the naval warfare branch of the People's Liberation Army, which is the armed wing of the Communist Party of China and, by default, the national armed forces of the People's Republic of China.
 The PLAN can trace its lineage to naval units fighting during the Chinese Civil War and was established in September 1950.
 Throughout the 1950s and early 1960s the Soviet Union provided assistance to the PLAN in the form of naval advisers and export of equipment and technology.
 Until the late 1980s, the PLAN was largely a riverine and littoral force (brown-water navy).
 However, by the 1990s, following the fall of the Soviet Union and a shift towards a more forward-oriented foreign and security policy, the leaders of the Chinese military were freed from worrying over land border disputes, and instead turned their attention towards the seas.
 This led to the development of the People's Liberation Army Navy into a green-water navy by 2009.
 Before the 1990s the PLAN had traditionally played a subordinate role to the People's Liberation Army Ground Force.
The Maze Prison escape (known to Irish republicans as the Great Escape) took place on 25 September 1983 in County Antrim, Northern Ireland.
 HM Prison Maze (also known as Long Kesh) was a maximum security prison considered to be one of the most escape-proof prisons in Europe, and held prisoners convicted of taking part in armed paramilitary campaigns during the Troubles.
 In the biggest prison escape in UK history, 38 Provisional Irish Republican Army (IRA) prisoners escaped from H-Block 7 (H7) of the prison.
 One prison officer died of a heart attack as a result of the escape and twenty others were injured, including two who were shot with guns that had been smuggled into the prison.
 The escape was a propaganda coup for the IRA, and a British government minister faced calls to resign.
 The official inquiry into the escape placed most of the blame onto prison staff, who in turn blamed the escape on political interference in the running of the prison.
