Dave Brant is a retired career Naval Criminal Investigative Service (NCIS) special agent and executive.

[2] A twenty-page statement issued on July 7, 2004, describes a series of high-level meetings among the United States Department of the Navy's most senior lawyers, that were triggered by reports, from Brant, that the captives being held in the Guantanamo Bay Naval Base were being subjected to questionable interrogation techniques.

David Brant made a brief cameo appearance on the CBS drama NCIS playing a Special Agent of the same name in the episode "Frame Up" in Season 3.

He is asked by the character Leroy Jethro Gibbs (Mark Harmon) "I heard you were quitting" to which Brant responds "I like to refer to it as a lateral move into the recreational sector...Jethro" to which Gibbs explains to Mossad liaison officer Ziva David (Cote de Pablo) that it "...mostly means fishing and hitting a golf ball".

[5][6] After he left NCIS Brant worked as a security expert for the accounting firms Deloitte Consulting and BDO.
