The FV4007 Centurion was the British Main Battle Tank in service in the '50s & '60s. Though it was replaced by the excellent Chieftain in the MBT role, it continued to be used as a specialised vehicle, notably the FV4003 AVRE used by the Royal Engineers. The AVREs were equipped with a 165mm demolition gun and either a hydraulically-operated bulldozer blade or a mine plough.
They could carry fascine bundles, metal track rolls and tow the Giant Viper mine-clearance equipment or a trailer for another fascine. This variant had a five man crew. The vehicle was used in the Operation GRANBY of 1991 though they were retired soon after.
VM's who worked on Cent suffered from a little know medical condition known as "Centurian Arse". This was brought about by the shape of the gearbox top cover (it was a shallow triangle in profile, with the point at the top) splaying the unfortunate fitters butt-cheeks as he sat on the gearbox in order to repair the brakes or final drives. Older VM's with many years experience would even walk a bit funny as a result. Additionally, the Centurian ARV had a second, low-ratio reverse gear. The gearstick itself was situated between the drivers legs, gear changes were stiff at the best of times and needed a good shove the engage any gear. Selecting emergency reverse ensured that an unwary driver caught the gear-stick right in the love spuds. Always a fave joke to play on a newly-posted recce mech!!
