  air, missile, and rocket attack. This protection includes early warning, surveillance, tracking, and defense
  against tactical short-range targets through intermediate-range ballistic missiles. (See FM 3-01 and
  ATP 3-01.94 for more information on AAMDC planning and execution.)
  Signal Command (Theater) or Strategic Signal Brigade
  4-79. The theater army is the designated DOD executive agent for setting and supporting the theater
  communications and network infrastructure in all AORs. The theater army executes these responsibilities
  either through a signal command (theater) or strategic signal brigade assigned to support the AOR. Either
  unit provides connectivity to Defense Information Systems Network services up to secret classification. This
  connectivity includes establishing and operating the theater network architecture to support all joint and
  Army forces operating in an AOR.
  4-80. The signal command (theater) or strategic signal brigade provides oversight, leadership, and technical
  direction over the theater network and spectrum management support for all Army units across the theater.
  It also provides—
  (cid:122) Centralized management of data, voice, and video networks, including interfaces with joint,
  interorganizational, and multinational systems in the theater.
  (cid:122) Enforcement of global cybersecurity policies to support the CCDR and theater army commander.
  (cid:122) Oversight of units installing, operating, maintaining, and securing signal support systems and
  network interfaces to joint and multinational partner systems in theater.
  (cid:122) Establishment of mission priorities to ensure network capabilities are available to meet
  commanders’ information requirements.
  Theater Engineer Command
  4-81. The theater engineer command (TEC) supports the theater army by organizing and directing Army
  combat, general, and geospatial engineer assets to improve mobility, enhance survivability, enable force
  projection and logistics, build partner capacity, and develop infrastructure. The primary focus of the TEC
  during competition is to determine and build the needed infrastructure to facilitate deployment of U.S. forces,
  protect forward-stationed U.S. forces, and, where possible, build up the capabilities of allied and partner
  nations to withstand an initial assault by a peer threat. Examples of engineer activities the TEC directs are
  conducting route analysis and terrain analysis of potential assembly areas for large Army units like BCTs
  and identifying needed assets to construct dispersed base clusters in the rear areas to support logistics
  operations in the close area. When directed, the TEC also provides C2 for engineers from other Services and
  multinational organizations and provides technical oversight (quality assurance and surveillance) assistance
  for contracted construction engineers according to the relationships established by the JFC. (See FM 3-34 for
  more information on theater engineer commands.)
  Battlefield Coordination Detachment
  4-82. A battlefield coordination detachment (BCD) is a specialized, regionally focused Army element that
  serves as the senior Army operational commander's liaison with the air component. A BCD is co-located
  with the joint air operations center (JAOC), combined air operations center, or the Air Force air operations
  center.
  4-83. The BCD is the Army's interface for systems connectivity to the JAOC and for personnel integration
  with their JAOC counterparts. The BCD supports the land component command during large-scale combat
  operations. Army corps relay requirements and requests to the land component, who, in turn, relays land
  component requirements and requests for joint force air component support through the BCD. The BCD
  represents the joint force land component commander throughout the joint air tasking cycle in the JAOC.
  (See ATP 3-09.13 for doctrine on the BCD.)
  Theater Fires Command or Element
  4-84. An Army theater fires command or theater fires element provides C2 of assigned fires capabilities,
  serves as the senior organization assigned to a theater army to integrate allocated or assigned fires capabilities,
  and executes critical fire support functions. It develops and nominates joint targets across the theater. This
