G4 Branch

The Eurocorps relies on the support provided by the contributing nations. The nations and the multinational commander share the responsibility for the logistic support of operations.
Although it is the nations' ultimate responsibility to support their deployed units, the Commanding General holds sufficient authority over the logistic resources to employ and sustain forces in the most effective manner.
Working towards this goal, the G4 Branch is responsible for logistic plans and logistic assessments within the whole corps area. Furthermore, it directs divisional framework logistics in accordance with superior HQ echelons' policy and plans. To ensure logistic support, G4 coordinates with the superior command echelons, divisional and corps troops HQs and National Support Elements (NSEs) within its area of operations and commands corps logistic troops.

The G4 Branch comprises five sections with a total workforce varying from 30 in peacetime to 96 in Article V operations.
