Abatis

 

an obstacle of felled trees (with trunk diameters of 15 cm or more) in a criss-cross pattern with their tops facing the enemy. Abatis were widely used as a foundation for building abatis lines along the frontiers of the Russian state in the 16th and 17th centuries.

In the 20th century abatis were used as obstacles against enemy infantry and cavalry. They were usually reinforced with barbed wire and mines and covered by fire.
