. Sapper-engineering assault units were formed in 1943. By 30 May of that year, the formation of the first 15 brigades was completed. Most of these units were formed from existing combat battalions, well-proven in battle. In August 1943, assault engineer-sapper brigades arrived at the front. These were each composed of: • Brigade Command (40 people) • Command Company (87 people) • Motorized Engineer-Scout Company (101 people) • 5 Assault Engineer-Sapper Battalions (388 people each) • Light Bridging and Crossing Equipment Crew (36 people) During the formations of assault engineering brigades, all soldiers over 40 years of age were reassigned. The most distinctive piece of individual equipment used by soldiers of the assault engineering brigades was the SN-42 () steel breastplate. In December 1943, a procedure was developed for the combat utilization of assault formations. Assault brigades were sent into battle to facilitate key breakthroughs in fortified defensive lines by means of
combat engineering and sapping. Success in battle hinged on close coordination with infantry, armoured, mechanized, and artillery units. As soldiers of the assault brigades were not equipped with heavy small arms or their own artillery, they were immediately withdrawn after a successful breakthrough in the enemy lines to limit casualties. In the spring of 1944 the assault engineering brigades were supplied with
ROKS-3 flamethrowers. The 1st, 2nd, 4th, 10th, and 2nd Guards assault engineer-sapper brigades were supplemented with engineer-tank regiments including PT-3 () mine flails and OT-34 flamethrower tanks, each composed of three companies with 20 combat vehicles per company. By May 1945, the brigades pushed through the city of
Königsberg (now Kaliningrad), with the
city falling in a matter of days. Over the course of the Second World War 20 assault engineer-sapper brigades were formed, performing admirably in combat operations, and especially distinguishing themselves in the storming of cities, which was their intended purpose. == Legacy ==
