"[6] Rader went on active duty in September 1966 and was sent to Fort Bragg in North Carolina, the home of the regular Army Special Forces.

In January 1967 the two men's work was published as a report on "a computerized system for automatically notifying social scientists of new journal articles", ones in their area of interest.

[7] Frustrated with his Army experiences in February and March, on April 14, 1967, Rader heard about a large anti-war protest which was to take place the next day in New York City.

[4] At Sheep Meadow, Central Park, wearing his Green Beret uniform covered by a black ski jacket, he assembled with the group of draft card burners and their friends.

[4] A large number of people were attending or watching this rally, including anti-war activist Abbie Hoffman,[9] New York City policemen, FBI men, newsreel cameramen, reporters, photographers and passers-by.

[12] In May 1967 in response to the Sheep Meadow demonstration, 56-year-old anarchist intellectual Paul Goodman published a piece in The New York Review of Books sympathetic to draft-card burning.

"[13] In September 1967 with anti-war activist David F. Greenberg, he founded Chicago Area Draft Resisters (CADRE), an organization with links to the national protest movement.

In association with the National Mobilization Committee to End the War in Vietnam (The Mobe), Rader helped organize the "March on the Pentagon" held on October 21, 1967.

For this rally, Rader worked with Abbie Hoffman, David Dellinger, Jerry Rubin, William Francis Pepper, Carl Davidson of Students for a Democratic Society, Professor Robert Greenblatt of The Mobe, Lincoln Lynch of the Congress of Racial Equality, and Amy Swerdlow of Women Strike for Peace (WSP).

[16] He wrote to WSP to ask for bail donations and legal defense resources, urging the women to "get behind this fine group of young idealists, working not for themselves, but for the future of the race.

[12] CADRE helped organize Chicago area activities for March 1968 including a week of protest and a day of civil disobedience.
