Quick survey using DuckDuckGo in order as they appear — Trilogy does well — and no one else has the idea of “full-spectrum” HUMINT at the management level, Wikipedia gets it partly right at the source level.
— HUMINT, a syllabic abbreviation of the words HUMan INTelligence, refers to intelligence gathering by means of interpersonal contact, as opposed to the more technical intelligence gathering disciplines such as SIGINT, IMINT and MASINT. NATO defines HUMINT as “a category of intelligence derived from information collected and provided by human sources.” . . . Within the context of the U.S. Military, most HUMINT activity does not involve clandestine activities.

2004-05-02 J. David Galland, Iraq Intelligence Failure Was Unavoidable (DefenseWatch Magazine posted to Pravda.ru)
— The greatest problem that has directly contributed to shoddy information collection, regrettably confused for quality intelligence, was painfully predictable. Because of the nether-world trappings and demands of clandestine human intelligence (HUMINT) operations, our agencies years ago ran out of spies who can function in the nasty back alleys of the globe without compromise.
