Mark Pitcavage is a historian and critic of far right wing groups and an expert on the board wargame Advanced Squad Leader (ASL). He works with the Anti-Defamation League and was the creator of the now archived Militia Watchdog website. The site has been an archive since 2000 when Pitcavage took the position of Director of Fact Finding for the Anti-Defamation League.
 Militia Watchdog
The Militia Watchdog website was founded by Pitcavage in 1995 following the Oklahoma City bombing and operated until 2000. The site's subscription list, which mainly included law enforcement officers and other "watchdog" groups, is still being utilized by the Anti-Defamation League (ADL). The site also worked in cooperation with other "watchdog" groups such as The Center for New Community, The Center for Democratic Renewal, the Southern Poverty Law Center and the Simon Wiesenthal Center.(p34) Pitcavage's Militia Watchdog profiles have been used as a source for writers on militias and their activities. With the success of the Militia Watchdog project, Pitcavage was made the Director of Investigative Research for the SLATT program.(p34) The SLATT program is an FBI domestic intelligence gathering apparatus that utilizes both paid and unpaid informants, primarily from organizations such as the Southern Poverty Law Center and The Center for New Community. The SLATT program is funded by the Bureau of Justice Assistance (BJA) of the U.S. Department of Justice.
 Anti-Defamation League
The ADL absorbed Pitcavage's Miltia Watchdog group and now maintains the site as an archive of his work between 1995 and 2000.
 Commentator on terrorism, gangs, and extremism
In the late 1990s and early 2000s, Pitcavage was cited as a terrorism and extremism expert by mainstream media. In 2002, he was interviewed and quoted at length about prison gangs by the Southern Poverty Law Center. Pitcavage has given interviews for radio stations such as KCBS (AM). In 2006, a student radio station at St. Petersburg College interviewed Pitcavage for an episode titled "Militia Movement".
 Association with Michael A. Bellesiles
Pitcavage's work was cited by Michael A. Bellesiles as "invaluable to the development" of his partially fraudulent anti-firearms "history" book Arming America: The Origins of a National Gun Culture. Bellesiles subsequently lost his professorship over the book's erroneous and fabricated claims.
 Board wargamer
In 2002 and 2003 Pitcavage was the author of strategy and tactics articles for a magazine on board-gaming. Pitcavage hosts his own website regarding the board wargame Advanced Squad Leader (ASL). He was named an ASL Gaming Laurelist in 2008.
