  supported echelons. Linkage is achieved by fiber optic or copper wire or transmission services
  provided by supporting Army communications or host nation infrastructure.
  * Engagement control station. The engagement control station is the Patriot battery's control center
  for air battle management. It provides fire direction functionality for the battery. It remotely
  controls the radar and launchers during air battle operations. Additionally, it establishes tactical
  data links to the Patriot ICC and adjacent Patriot fire units via the Patriot digital information link
  (PADIL).
  * Battery command post. The battery command post operates in a manner similar to the tactical
  control station at the battalion. It directly supports the engagement control station during planning
  and air battle operations. It is also responsible for tracking battery-level force operations and
  equipment status and reporting these to the battalion. External elements link to the battery
  command post using standard protocols such as link 11 and link 16. The battery command post
  cannot transmit on links 11 or 16; it can only receive.
  THAAD
  B-6. THAAD is an anti-ballistic missile upper tier system that provides the capability to engage and negate
  short-, medium- and intermediate-range ballistic missiles within and outside the atmosphere. Engagements
  can be conducted against ballistic missiles in both the late midcourse and terminal phases of their trajectories
  (see FM 3-27 for more information on defense against ballistic missiles during their flight phases). THAAD
  is organized and deployed as a battery. THAAD is deployable and globally transportable via air, land, and
  sea. A THAAD battery consists of four main components. THAAD system components are air transportable
  by C-17 and C-5 aircraft. THAAD missiles require special authorization to ship and separate shipment (not
  on the launcher). For more information on the THAAD system see ATP 3-01.91.
  B-7. THAAD launcher. The THAAD launcher is a HEMTT-mounted, mobile, stabilized missile launch
  platform carrying a missile round pallet. The launcher has a high rate-of-fire and can be rapidly reloaded.
  The pallet contains eight hit-to-kill, passive terminal homing missile rounds per launcher. The THAAD
  missile round is a certified round composed of a canister and missile containing a single-stage booster and a
  kill vehicle. There are six launchers in a THAAD battery. Figure B-3 shows a THAAD launcher and missile
  round at launch.
