The Python Minefield Breaching System is used by the British Army to clear minefields. It replaces the Giant Viper, and has the ability to clear a safe lane in minefields 180–200m long and 7.3 m wide through which vehicles can pass. Python has been used operationally with the Trojan AVRE in Afghanistan. During Operation Moshtarak the Royal Engineers attempted to use this traditional mine clearance equipment in the Counter-IED role in support of a major British Army advance.
