  Klingon naval enlisted rank insignia follow the pattern
  of the other services, with one large triangle for junior
  personnel and two for senior personnel. Unlike the
  Army, there is no distinction between Tech Masters
  and Technicians. Unlike the Army and Marines, there
  is no “branch” color and all technicians have double
  yellow triangles. Technicians are divided into types:
  engineering, operations (weapons, communications,
  navigation), pilots, and medical.
