Reihe: Weapons and Equipment of the Warsaw Pact

The ability to advance rapidly over sometimes difficult terrain was a key part of the Warsaw Pact's strategy. The Eastern European nations which formed this historic alliance wanted to be able to move quickly and effectively so they didn't give their enemies an advantage.
The vital tools which helped the Warsaw Pact overcome the challenges it faced included a whole range of combat engineering equipment. This book is a factual reference of the equipment which was used throughout the Cold War period and the important roles each piece played.
With obstacles including rivers and minefields to negotiate, combat units could have faced costly delays if it hadn't been for the diligent work of the Warsaw Pact's engineers. Refusing to allow troops to be slowed down by the landscape, these combat engineers worked in sometimes challenging conditions to find safe routes to their destination.
From building bridges and clearing safe lanes through minefields to repairing and recovering broken down vehicles and creating field fortifications, the work of these engineers played an essential part in the Warsaw Pact's military strategy.
But the work of this effective force would have been impossible without the specialist engineering equipment they used. Rugged, simplistic compared to their Western equivalents, these items would play a crucial part in both peacetime military exercises and combat operations in Afghanistan.

River Crossing
During the Cold War, the Soviet army studied the disposition of rivers in Western Europe. It concluded that they would have to cross water obstacles up to 100m wide every 35 to 60km. Every 100 to 150km, they would encounter a water obstacle between 100m and 300m wide. Every 250 to 300km, they would encounter one that was wider still. In a war in Western Europe, the Soviet army expected to advance an average of 100km per day, leading to a significant number of river crossings. NATO would obviously try to destroy bridges to slow the advance. Therefore, the Warsaw Pact armies put a great deal of emphasis on their ability to cross water obstacles quickly and efficiently. A range of equipment was created to bridge gaps or ferry vehicles over rivers. River reconnaissance systems were developed to quickly measure water depth and river width. Some of these were mounted on sleds that were towed behind boats or amphibious vehicles. Many light armoured vehicles could swim. Main battle tanks carried snorkels that allowed them to wade through water up to five metres deep. Most river crossings would have been assault crossings from the march, at sites that were only lightly defended, if at all. Reconnaissance patrols, equipped with specialised equipment, would find suitable sites. These would be up to platoon size, and operated up to 50km ahead of the main body. When a crossing site had been selected, a forward detachment would secure the site. This detachment would be two to three hours ahead of the main body, and would avoid enemy contact. A typical forward detachment would consist of a motor rifle battalion with an attached tank company and artillery battalion. Amphibians, ferries, air defence, anti-tank, and chemical defence units would also be attached. Heliborne, or occasionally airborne, troops could also be used in this role. If the crossing site was defended, the attack would be carried out with significant artillery and air support. River crossings got priority for air support, and were considered particularly vulnerable to enemy air attack. Air defence assets would be deployed close to the crossing site, and would cross the river as soon as feasible to extend their coverage. The crossing itself would be carried out by APCs or IFVs swimming across the river, supported by tank and artillery fire from the near shore. A few tanks may have crossed in the first wave, but most would provide fire from the near bank and cross later. Artillery and anti-tank units would cross immediately after the infantry to provide support in holding the bridgehead. Tanks would cross using ferries, bridges, or by snorkelling. Snorkelling
The ability to wade, or snorkel, through water up to 5m deep was a standard feature in Soviet main battle tanks. It seems likely that ferries or bridges were the preferred method of crossing water obstacles. That said, a 1971 British army intelligence report stated that the Soviet army considered snorkelling "a practical operation of war". Every tank crew was fully trained in it. Training took place on purpose-built sites with good facilities. Emphasis was placed on ensuring the crew were confident in their ability to snorkel well and safely. Training was split into two phases. The first phase, lasting up to two months, concentrated on preparing the crews to operate tanks under water. Training covered swimming, diving, and carrying out procedures underwater whilst wearing escape masks. There was a good deal of safety training, which helped with crew confidence and morale. Rescue operations were practised on simulators. Crews were not allowed to move onto the second phase until they had passed this first phase. In the second phase of training, the crew put their skills to the test. A five-metre deep lake was used to practice driving underwater. Initially, drivers would drive 90m underwater, progressing to 150m as their skills improved. At least some sites also had facilities for blind driving, with the driver guided only by the tank's gyro compass. After passing this second phase of training, crews would join their units. Sealing and preparing a tank for snorkelling could take as little as 15 minutes. Older tanks took longer, up to half an hour. This would be done in a concealed area 3 to 5km from the river. When the tanks got to within 1 to 2km of the river, snorkels would be fitted. Tanks crossed at slow speed, in a column formation, with a 30m gap between vehicles. Drivers would not change gear or stop while in the water. Once across, the tank would have to stop while the crew removed the waterproofing. Until this was done, the turret could not be traversed or the gun fired. If a tank stalled in the river, the crew would flood the vehicle, then escape through the hatches. An alternative method of snorkelling used winches to pull unmanned tanks across. A pair of armoured recovery vehicles would set up on the far bank with a pulley block and anchoring unit. Up to three tanks could be pulled across the river simultaneously. Using this method, a 10-tank company could cross a 200m-wide river in 35 minutes, assuming the tanks had already been sealed. The crews would cross separately, either in amphibious vehicles such as APCs, or on boats. Snorkelling was not to be carried out under fire, and in some cases the banks would make it impossible. The entry bank had to have a slope of less than 25º, the exit bank one of less than 15º, and the current no more than three metres per second. In winter, drifting ice could damage the snorkel. The river bottom had to be reasonably firm, and free of boulders and craters. Swimming
Many lighter AFVs were amphibious, and could swim across water obstacles. All APCs from the BTR-50 onwards, and all IFVs, were fully amphibious. The BRDM series of reconnaissance vehicles, and even some self-propelled artillery and AA vehicles, could swim. Many were propelled in the water by their wheels or tracks, although some used water jets to achieve better performance in the water.
BTR-80 Swimming Water obstacles would only be crossed under fire as a last resort. In these cases, a great deal of artillery would be called upon to support the operation. If at all possible, helicopter troops would be landed on the far bank, and attack simultaneously with the crossing. Tanks would stay on the near bank to provide covering fire, while amphibious armoured vehicles swam across. Once a bridgehead was established, tanks and other vehicles would snorkel or be ferried across. These would then continue the advance, while engineers used pontoons to make a permanent bridge crossing. Vehicle-Launched Bridges
Soviet estimates found that two-thirds of the river obstacles they would encounter in Europe were less than 20m wide. This led to the development of vehicle-launched bridges capable of quickly crossing these narrow gaps. The Polish army developed a tracked bridge, which was pushed into place by a tank. Small numbers of a T-34-based bridging tank were delivered to the Soviet army in 1957. This was soon superseded by the MTU-54, sometimes referred to as the MTU or MTU-1. MTU-54
In 1958, the MTU-54 was introduced, based on a T-54 chassis. This mounted a simple 12.3m bridge, carried horizontally. Unlike later vehicles, the bridge was not folded for transit. To launch, a chain-drive mechanism moved the bridge forward, before it was lowered into place. This method had the advantage of keeping the silhouette low during launch and recovery operations. The MTU-54 could bridge an 11m gap, and had a load capacity of 50 tonnes. Launch time was three to five minutes, and recovery could take place from either end of the bridge.
MTU-54 It was fitted with a DShKM machine gun for defence, mounted in the centre of the vehicle. This had to be removed before launching the bridge. Later vehicles were fitted with a deep-wading snorkel, NBC protection, and automatic fire-suppression system. Specifications: MTU-54 Crew: 2

MT-34 (Czechoslovakia)
Introduced in 1960, the Czech MT-34 mounted a scissor bridge on a T-34-85 chassis, with a boxy superstructure holding the cable winches and hydraulic units. A contemporary of the Soviet MTU-54, the bridge was much shorter than the Soviet design when in transit, making it less cumbersome. It was much easier to spot when launching, however, since the bridge was raised to vertical before being unfolded into place. It had a bow mounting for a 7.62mm DTM machine gun, but the machine gun was not usually fitted. The system served with various Warsaw Pact armies, in addition to the Czech army.
