described in 1978, "The FBI compiled other lists in addition to the
Security Index. These include a "Comsab program" (concentrating on Communists with a potential for sabotage), and "Detcom program" (a "priority" list of individuals to be arrested), and a
Communist Index (individuals about whom investigation did not "reflect sufficient disloyal information" but whom the bureau deemed to be 'of interest ... '.")

Secrecy

Long-time FBI head
J. Edgar Hoover wanted the program to remain secret from the public:
He thus instructed his top agents that "no mention must be made in any investigative report relating to the classifications of top functionaries and key figures, nor to the Detcom or Consab Program, nor to the Security Index or the Communist Index. These investigative procedures and administrative aids are confidential and should not be known to any outside agency."
Description

Most sources take "DETCOM" to stand for "
DETain
sCOMmunist" (bolding added):
* 1976 -Select Committee to Study Governmental Operations, United States Senate: "The Emergency Detention Program, 1946-1950": The development of plans during this period for emergency detention of dangerous persons and for intelligence about such persons took place entirely within the executive branch. In contrast to the employee security program, these plans were not only withheld from the public and Congress but were framed in terms which disregarded the legislation enacted by Congress. Director Hoover's decision to ignore Attorney General Biddle's 1943 directive abolishing the wartime Custodial Detention List had been an example of the inability of the Attorney General to control domestic intelligence operations. In the 1950s the FBI and the Justice Department collaborated in a decision to disregard the attempt by Congress to provide statutory direction for the Emergency Detention Program. This is not to say that the Justice Department itself was fully aware of the FBI's activities in this area. The FBI kept secret from the Department its most sweeping list of potentially dangerous persons, first called the "Communist Index" and later renamed the "Reserve Index," as well as its targeting programs for intensive investigation of "key figures" and "top functionaries" and its own detention priorities labeled "Detcom" and "Comsab".
* 1995 – M. Wesley Swearingen wrote: DETCOM was part of J. Edgar Hoover's (in)famous Security Index. "I became very knowledgeable about the Security Index, because all my subjects were tagged either DETCOM ("detain as communist") or COMSAB. COMSAB was the designation for someone who had a job in a company with government contractss, and who therefore had an opportunity to commit sabotage in the event of a national emergency. Subjects tagged COMSAB were to be arrested first, then those tagged DETCOM, followed by all others on the Security Index. After all the individuals on the Security Index were arrested, those on the Communist Index, later called the Reserve Index, were to be arrested."
* 2003 – Fred Jerome wrote: "In the early 1950s, congressional committees were keenly interested in hearing how many hard-core communists Hoover was prepared to put into "detention camps" in case of a war with Russia. This was the "Detention of Communists"–or Det-Com–lst. While the FBI had millions of security files, "only" several thousand were slated for such emergency camps. The purpose of Det-Com,
David Wise explains, was simply "to determine which of us to lock up in the event of war or a presidentially decreed 'emergency'." On September 7, 1950 (the day G-2's first

spy-memo arrived), Hoover told the senators the FBI had targeted twelve thousand Reds to be rounded up "in the event of war with Russia." The ''Washington Post'' reported the next day that he also requested funding for 835 new agents and 1,218 new clerical workers ... How many people were actually in Hoover's Det-com file? It wasn't a small number. Former FBI official Neil Welch says there were 'thousands'."
* 2015 – Meredith Owen wrote: "The "detention of Communists" program, or DETCOM, tracked potential subversives and established a "Master Arrest Warrant" that would have made arrests easier if they became necessary, though over the course of the several decades that the FBI continued the program, the warrant was never used. The list included thirty-six Chinese aliens, a tiny fraction of the population, but enough to raise questions about Chinese residents' loyalties.
List
By 1951, the FBI had formalized the program: "Forms beginning in 1951 included a space labeled "Tab for Detcom" and "Tab for Comsab."
[
