  saying that might add credence or doubt as to the veracity of the statements.
  For example, the interpreter could point out that although the source claims
  to be a factory worker, his language use indicates that the source has a
  university education. In another example, the interpreter could indicate that
  the dialect or pronunciation that the source is using does not match the area
  that he claims to be from. During report writing, the interpreter supports the
  HUMINT collector by not only answering questions on the literal
  interpretation but also adds, when appropriate, comments on the significance
  of both what was said and how it was said.
  SOURCES OF INTERPRETERS
  11-13. There are almost never sufficient interpreters to meet all unit mission
  requirements. Interpreters in support of HUMINT collection require a
  security clearance and knowledge of the operational situation. While any
  qualified interpreter can be used to support HUMINT collection, the
  HUMINT collectors maximize the collection potential if the interpreter has
  received specific training. The number of interpreters needed to support a
  HUMINT collection mission is METT-TC driven based primarily on the
  number of HUMINT collectors, the dispersion of the HUMINT collectors in
  the AO, and the number of sources. Normally one interpreter for every two
  non-language qualified HUMINT collectors is sufficient; however, in
  situations where a large number of high-value sources must be questioned in
  a limited time, a ratio of 1 to 1 may be required. Interpreters are obtained
  from within the military and from the US and local civilian populations or
  other English-speaking countries.
  MILITARY
  11-14. There are many soldiers, including non-US citizens, who have native
  language abilities due to their upbringing. Their parent unit may identify
  these language abilities, or these soldiers may volunteer their abilities when
  a contingency arises. The ARNG, USAR, other US military services, and even
  coalition militaries, have language-trained and certified personnel in
  Military Intelligence MOSs, such as 98G or 09L, who may be called upon to
  serve as interpreters for the HUMINT collection effort.
  CIVILIAN
  11-15. Civilian corporations may be contracted by the military to provide
  interpreters for an operation. These interpreters are divided into three
  categories:
  • CAT I Linguists - Locally hired personnel with an understanding of the
  English language. These personnel undergo a limited screening and
  are hired in-theater. They do not possess a security clearance and are
  used for unclassified work. During most operations, CAT I linguists are
  required to be re-screened on a scheduled basis. CAT I linguists should
  not be used for HUMINT collection operations.
  • CAT II Linguists - US citizens who have native command of the target
  language and near-native command of the English language. These
  personnel undergo a screening process, which includes a national
