Tank bridge laying machine M60 AVLB
This is probably the most famous car of its kind: in less than 8 minutes it can build a bridge with a length of 18 meters, through which 60-ton machines can pass. He inherited the armor from the M60А1 battle tank, so he can go alongside the combat vehicles, allowing them to overcome anti-tank ditches and small rivers.
Self-propelled ferry EFA
This French car is a folding ferry on a wheeled chassis. By hooking up a few pieces, you can get a full-fledged pontoon bridge through which heavy equipment will pass.
Digging trenches is much more effective not with a shovel, but with the wheel of such a Russian (Soviet) TMK trench machine. At the disposal of the infantry, as a rule, small shovels (those that are called deminers in everyday life), which they dig slowly and hard. TMK will do what the motorized infantry unit digs out in a day's 2 − 3 in 20 minutes.
