How to buy a tank

Since, in Fast & Furious 6, the tank I’m driving would see quite a bit of car-crushing action, the producers calculated it would be cheaper to add some protection it rather than stop filming every couple of flattened cars or so to patch it up.

In fact, this tank is still crushing cars – as I’m reminded when, churning through the thick mud, I see a line of around 40 flattened wrecks at the side of the field. For a second I wonder if I’ve taken a wrong turn through the car park…

Starting the Chieftain is a straightforward affair. You fire up the 2.0-litre diesel generator that supplies the electrical power and then flick the three switches that trigger the main fuel pumps, press the starter button and the 19-litre, opposed-piston two-stroke diesel engine roars into life.

It’s an interesting motor for having two opposing pistons per cylinder, each with its own crankshaft and, depending on its location, each in charge of an outlet or inlet port. It produces 950bhp and, being a multi-fuel engine, can run on whatever juice is to hand, from Shell V-Power to vodka. Down at your feet are an accelerator pedal and a brake pedal but you’ll look in vain for a clutch or even a gearstick. In fact, if you’re a biker you’ll like the Chieftain because you shift gear using a foot change like a motorcycle’s. Curiously, though, you have to change gear up the ’box but it changes for you going down. If all that leaves you seriously confused, the gear you’re in is displayed on a small gauge set in the instrument binnacle, just below the hatch. That’s doubly useful because the Chieftain has not one but two reverse gears.

Steering is achieved by pulling and pushing on levers either side of you. Pull the right lever to brake the right track and go right, and vice versa, although when going in reverse you operate the opposing lever, which is difficult to get your head around at first. You must pull the lever firmly and deliberately, since anything less risks burning out the huge discs and pads that brake the tracks.

I’m sitting in a conventional seat but were this a standard Chieftain, I’d be lying almost on my back with the hatch closed and looking out through a periscope – a chilling prospect if this muddy Northamptonshire field were a real battle ground.

With the engine running I select first gear – and nothing happens. The sheer weight of the tank prevents it from moving. So I feed in a bit more gas and 70 tons of Chieftain Mk10 creeps smoothly forward over the field as if it were a parade ground.

With the revs building I glance down at the foot change and toe the ’box into second. The indicator needle flicks to the next number obligingly. I change up to third before trying a few changes of direction with the track brakes. The tank responds immediately and precisely.

My attempts to steer it around its own axis – called a neutral turn – are thwarted since the Chieftain requires maximum power and near-perfect conditions to contra-rotate its tracks. Still, it can out-turn most cars, which is necessary if it is to dodge enemy fire or, if I’d seen them, a set of aluminium ladders.

Despite the tank spending its days crawling around at walking speeds crushing cars, the engine has proved to be perfectly reliable. Nevertheless, Mead’s ears are permanently tuned to unfamiliar noises emanating from it. He’s particularly alive to the possibility of the supercharger seals failing, resulting in the engine ingesting 35 gallons of its own oil and, as a final flourish, ejecting its 12 pistons into the crew compartment.

It’s not a pleasant prospect to contemplate and, discretion being the better part of valour, I decide to return the Chieftain to its parking spot and have a play in Mead’s offroad Bentley GT instead.

It’s parked among an array of tanks, Abbott self-propelled guns, armoured personnel carriers and even a mighty Ural-4320 6x6 diesel, currently for sale and with a camper conversion in the back. Another of the vehicles, an Alvis Stormer purchased from Northern Ireland, still has elements of its Starstreak missile system attached to it.

Mead began collecting tanks 30 years ago when he bought a couple costing £3600 apiece. He was a butcher at the time but the fact that you could buy a barely used tank, which cost millions of pounds new, for just a few thousand intrigued him. He could only see their prices going one way and sure enough they have, as private collectors from all over the world pile in.

“I’ve another Chieftain here that’s worth £40,000 today but next year it’ll be £45,000 and the year after that, £50,000,” says Mead.

He has 180 tanks, mostly British, on his 100-acre site. Four of them are Chieftains, for sale at prices ranging from £18,000 to £50,000. Buying a tank is straightforward enough but Mead has to be careful who he sells to. “I can go to prison if I sell to the wrong country,” he says.

It’s not only collectors who value Mead’s tanks. He’s just back from providing some of them to the British Army for its annual demonstration of firepower. They included some of his Russian tanks and a Mitsubishi L200 pick-up he’s converted into a rebel mobile rocket launcher.

“They like to have alien vehicles to target so they can practise vehicle recognition and tell friend from foe on the battlefield,” he says.

What would the army make of Mead’s Bentley GT W12? The ‘Dakarinspired off-roader’ was created by TV’s Supercar Megabuild team, who fitted it with raised and stiffened suspension, extended wheelarches, crash bars and a rear screen-mounted spare wheel, before painting it a drab shade of green. It was sold at auction in 2017 and now resides at Tanks-Alot, sporting an undignified advertising hoarding on its roof.
