Challenger 2 tank An important weakness of abatis, in contrast to
barbed wire, is that it can be destroyed by
fire. Also, if laced together with
rope instead of
wire, the rope can be very quickly destroyed by such fires, after which the abatis can be quickly pulled apart by
grappling hooks thrown from a safe distance. An important advantage is that an improvised abatis can be quickly formed in forested areas. This can be done by simply cutting down a row of trees so that they fall with their tops toward the enemy. An alternative is to place explosives so as to blow the trees down. Abatis are rarely seen nowadays, having been largely replaced by
wire obstacles. However, it may be used as a replacement or supplement when
barbed wire is in short supply. A form of giant abatis, using whole trees instead of branches, can be used as an improvised anti-
tank obstacle. == See also ==
