Such work was a vital factor in opening and maintaining routes of communication which contributed to supply support of combat operations.The 84th Engineer Construction Battalion displayed such outstanding devotion and superior performance of exceptionally difficult tasks as to set it apart and above other units with similar missions".



B: Second Award: "Charged with the mission of constructing a vital and strategic bridge, the Battalion undertook its task with superior aggressiveness and determination.Although constantly confronted with difficulties inherent to combat conditions and natural hazards,the willingness to assume responsibility on the part of each individual enabled the Battalion to overcome the most formidable obstacles.The structure,believed capable of withstanding seasonable floods,is a vital link in the communications system."
