The Giant Viper used rockets to launch a 250-metre-long hose, packed with plastic explosive, across a minefield.
In the 1970s, the Giant Viper hoses were filled at ROF Chorley.
For safety, a vehicle fitted with a mine plough is driven through the cleared path before any other personnel, in order to push any undetonated mines safely out of the way.
It improves accuracy of delivery, deployment speed, and the size of the cleared path, which is now 230 metres long and 7 meters wide.
The Hellenic Army's Engineer Corps still utilize the system.
