  Contract Interrogators
  INTRODUCTION
  K-1. Contractors are used increasingly to augment existing capabilities and
  bridge gaps in the deployed force structure. With the increased use of
  contractors comes the need to identify the doctrine and procedures affecting
  their employment. Leaders and those working with contractors must
  understand that contractors are civilians authorized to accompany the force
  in the field and should be provided with an ID card as proof of their
  authorization. In accordance with GPW Article 4, contractors are to be
  accorded POW status if captured.
