When the U.S. Army wants a bridge built, they want it done fast. Luckily, they have the M60 AVLB (Armored Vehicle Launched Bridge). As you can see in the video below, it takes just about a minute and a half for the tank to lay down a bridge.
Bridge-laying tanks have a long history, vital in getting armor and artillery across rivers and other obstacles. The British and French used early versions of armored vehicle-launched bridge tanks in World War I as a way to advance in a time of trench warfare.
During World War II, when battles often swung on who could get their armor into position faster, AVLBs became indispensable, with both Axis and Allied forces deploying several versions of AVLBs, with the Churchill infantry tank being perhaps the most famous.
The M60 AVLB is actually not the newest model of AVLB used by the U.S. Army. The M104 Wolverine, built around the faster and more modern M1A2 chassis, was developed in the 1990s and production models were delivered by 2003. But budget cuts and a shift towards a faster, lighter form of armored combat within the U.S. Army meant that only 44 were put into production. Meanwhile, the Marines still keep 55 of the M60 AVLBs around, and sales to Isreal, Pakistan, Singapore, and Spain mean that there are nearly 100 of these still in operation.
