Barrage is a military term covering a wide range of structures, devices, or measures for destroying something to constrain or impede the movement of troops and forces.
Military barrages may be set up on land, in the water, or in the air to damage enemy forces, to impede their movement, to delay or restrain their actions, or to force them to move in a favorable direction for friendly troops.[1][2][3][4]
Barrages can be erected both in advance and during combat; they can be created in the support zone, on the approaches to defensive lines, in front of their front edge and in the depth of tactical and operational defense zones. Construction of barrages is subject to the intended plan of the battle (operation) and is closely coordinated with the fire system and strikes of the means of fire, taking into account the maneuvering of their forces.[1][3][4]
For all barrages reporting documentation is drawn up in the prescribed form; during the change of troops the erected barrages are handed over by act with the reporting documents attached to it.[1]
