the Germans formed a specialized unit called the Rohr Battalion to develop assault tactics. During the Brusilov Offensive of 1916, the Russian general Aleksei Brusilov developed and implemented the idea of shock troops to attack weak points along the Austrian lines to effect a breakthrough, which the main Russian Army could then exploit. The Russian Army had also formed hunter commando units in 1886, and used them in World War I to protect against ambushes, to perform reconnaissance and for low-intensity fights in no-man's-land. The von Hutier tactics (infiltration tactics) called for special infantry assault units to be detached from the main lines and sent to infiltrate enemy lines, supported by shorter and sharper (than usual for WWI) artillery fire missions targeting both the enemy front and rear, bypassing and avoiding what enemy strong points they could, and engaging to their best advantage when and where they were forced to, leaving decisive engagement against bypassed units to following heavier infantry. The primary goal of these detached units was to infiltrate the enemy's lines and break their cohesion as much as possible. These formations became known as Stoßtruppen, or shock troops, and the tactics they pioneered were the basis of post-WWI infantry tactics, such as the development of fire teams. Notwithstanding the postwar status of the Storm Troopers in German service, the same sort of tactical doctrine was widely espoused in British and French service in late 1917 and 1918, with variable results. The British Army standard training manual for platoon tactics, SS 143, was used from February 1917 onwards and contained much of what was standard for German shock troops. According to Ward, the Australian and Canadian divisions deployed amongst British forces in France quickly came to be regarded as the best shock troops in the Allied ranks due to their ferocity in battle, and were employed accordingly. US forces were trained in tactics by surviving French cadre from chasseur units, and were trained to use French Chauchat light machine guns and rifle grenades. World War II During the Second World War, the Red Army of the Soviet Union deployed five shock armies ( – singular: ) between 1941 and 1945. Many of the units, which spearheaded the Soviet offensives on the Eastern Front from the Battle of Stalingrad (1942–1943) to the Battle of Berlin (1945), were shock armies. Shock armies had high proportions of infantry, engineers, and field artillery,
