  Patriot missiles capable of long-range, low-to-high altitude, all-weather defeat of close-, short-, and medium-
  range ballistic missiles and the other threat types mentioned above. Patriot provides both lower tier ballistic
  missile defense and air defense. Figure B-2 shows a Patriot launching station.
  B-4. Three types of Patriot missiles are employed, all of which are certified rounds: Patriot Advanced
  Capability (PAC)-3 cost reduction initiative missile (hereafter referred to as PAC-3), PAC-3 missile segment
  enhancement (hereafter referred to as the missile segment enhancement missile), and guidance enhanced
  missile. The PAC-3 missile is a medium-range, low-to-medium altitude, radio frequency, terminal homing
  hit-to-kill missile. The missile segment enhancement missile is a radio-frequency terminal homing, extended
  altitude and range, hit-to-kill missile. The guidance enhanced missile is a medium-to-long range, low-to-high
  altitude, semi-active guided missile optimized against cruise missiles and other air threats. Patriot launchers,
  depending on version/configuration, can mount 16 PAC-3 missiles, 12 missile segment enhancement
  missiles, 4 guidance enhanced missile, or a mixed load. Patriot missiles require a Patriot radar to provide
  uplink commands for midcourse guidance (PAC-3 and missile segment enhancement missiles) or for the full
  engagement sequence (guidance enhancement missiles).
