Counterintelligence Field Activity (CIFA) is part of the U.S. military and is in charge of gathering information about people and activities that might pose a threat to the U.S. and its security. CIFA collects all sorts of information, like who people are talking to and what kind of activities they are involved in, to make sure that the U.S. is safe from any bad people or things. To do this, CIFA works with other government agencies and the military to make sure that all the information it gets is correct and up-to-date. Then, CIFA and the other agencies can use this information to help keep our country safe.
