Barrage

 

a type of artillery fire used to repulse attacks and counterattacks by enemy infantry and tanks; it is applied suddenly and without warning to lines (or sectors) outlined in advance and is usually ranged. Barrages are divided into frontal and flanking fire, according to their direction relative to the front of friendly units. Remoteness of the closest edge of the barrage from friendly units that are hot sheltered guarantees their safety. The depth of barrage sectors usually reaches 150–200 m. When the enemy leaves the barrage sector, the fire is switched to the next line. Barrages may be used by antiaircraft artillery and antiaircraft machine guns to destroy aerial targets.

Barrage

 

a hydroengineering regulating structure designed for the partial or complete damming of secondary river branches in order to increase the flow rate in the main channel. Barrages are used in mountain streams to decrease bottom slopes (underwater gradients) and to halt stream channel erosion. Barrages are constructed in the form of rock-fill walls, fascines, or gabions.
