text: Engineer Echelon Perspectives
  the selected activities demanded by engineer requirements, they must remain synchronized with their staff
  counterparts in the broader operations process.
  TECs synchronize engineer effort throughout the theater. Through their persistent engagement with
  the geographic combatant commands, each TEC is routinely involved in various military engagements with
  associated theater army headquarters. For other major operations, the theater army engineer collaborates with
  the TEC commander and staff as planning proceeds. Significant determinations included in the force
  generation effort are timing and the level required for the deployment of TEC capabilities. For large-scale
  ground combat, the theater army echelon typically requires the early or phased deployment of the full TEC
  headquarters. Stability and DSCA vary but may require the deployment of the supporting TEC or its
  deployable CP. Figure 6-1 shows phased-deployment capabilities to task alignment of the TEC and its
  deployable CPs.

  The TEC commander serves as the senior in-theater engineer. The TEC is the preferred organization
  designed for the operational command of engineer capabilities at echelons above corps and often provides
  C2 for the joint force command if an operational echelon engineer headquarters is required. The TEC is
  focused on the operational C2 of engineer operations across all engineer disciplines and typically serves as
  the senior theater or land component engineer headquarters. When directed, the TEC 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 joint
  relationships established by the joint force command. The theater army operationally configured as a land
