An abatis is a field fortification consisting of tree branches positioned in a row with sharpened ends facing outwards toward the enemy. They may be constructed of entire branches or pointed logs and are intended to block or slow an enemy advance. Though largely replaced by wire obstacles, military engineers are still trained in their construction.
