I am surprised USFK did not already have a unit dedicated to doing human intelligence analysis already:

The U.S. troops in South Korea are pushing to set up a unit that will be charged with gathering and analyzing human intelligence on North Korea, local authorities said Sunday.

Human Intelligence, known as HUMINT, is intelligence gathered by means of interpersonal contact.

The move comes as the North’s development of communications security technology is increasingly making signals surveillance of the country’s internal communications more difficult.

According to the authorities, the U.S. Forces Korea (USFK) plans to create a specialized unit around October under the 501st Military Intelligence Brigade of the Eighth U.S. Army. The new unit will be called the 524th Military Intelligence Battalion, they said.

In the brigade, the 532nd Military Intelligence Battalion is in charge of human intelligence affairs, but its main duty is analyzing intelligence, not directly gathering it.  [Korea Times]
