On Exercise Eagles Sapper on Salisbury Plain, the sappers gave an explosive demonstration of their ability to adapt and overcome by creating an abatis - a field fortification using trees to create an obstacle to delay or block the enemy's advance. While the use of abatis can be traced back to Roman times, explosives have replaced axes to fell the trees and turned a static fortification into a trap that can be sprung to seize the tactical initiative.
We have to have a mind-set of improvisation.
Captain Rob Palmer said: “An abatis is incredibly simple, and that’s why it works. We’d set the charges and then as the enemy approaches detonate them to create an obstacle across their route, which either delays the enemy’s advance or puts them in a fixed position where they can then be attacked.
“As airborne engineers, we’re restricted by weight on what equipment and stores we can parachute in with, so we have to have a mind-set of improvisation. The trees that we’d use to make an abatis are on the ground already so all we need to bring is plastic explosives, which in itself is very versatile and used for a lot of other tasks.”
The sappers parachuted in to start the two-week-long exercise which has tested the full spectrum of their combat engineering skills, from demolition to water supply, to confirm their readiness to deploy at short notice on operations around the world.
The trees felled during the exercise were earmarked for felling as part of forestry management on Salisbury Plain.
