At first glance you're right. They were also quite effective in the role they were designed for. The big thing about them was the people in them should have also been issued back/kidney braces.

Why would you issue the wankers a ‘back/kidney brace’ ? If they didnt want to ride around all day sitting on their asses they could have joined the infantry.
 
I am wondering if that is some of Rommel's Asparagus in the near background there. Would sort of be an odd place in the middle of what looks to be a field, for them to be utility poles.

Casual dress, clean vehicle with no ration boxes or fuel cans piled all over it, I would say England and those are Churchill's anti paratroop obstacles that the English put in every open space in 1940/41. They once had wire strung between them to make life hard on the airborne guys.

The 15 inch pneumatic cannons of the USS Vesuvius.

Vesuvius carried three 15-inch (38-cm) cast iron pneumatic guns, invented by D. M. Medford and developed by Edmund Zalinski, a retired officer of the United States Army. They were mounted forward side-by-side at a fixed elevation of 16 degrees. Gun barrels were 55 feet (17 meters) long with the muzzles extending 15 feet (4.6 meters) through the deck 37 feet (11 meters) abaft the bow. In order to train these weapons, the ship had to be aimed, like a gun, at its target. Compressed air from a 1000 psi (70 atm) reservoir projected the shells from the dynamite guns. Two air compressors were available to recharge the reservoir.[1]

The shells fired from the guns were steel or brass casings 7 feet (2 meters) long with the explosive contained in the conical forward part of the casing and spiral vanes on the after part to rotate the projectile. The explosive used in the shells themselves was actually a "desensitized blasting gelatin" composed of nitrocellulose and nitroglycerine. It was less sensitive to shock than regular dynamite but still sensitive enough that compressed air, rather than powder, had to be utilized as the propellant. Shells containing 550 pounds (250 kg) of explosive had a maximum range of 1 mile (1.6 km), but range could be extended to 4000 yards (3.7 km) by reducing projectile weight to 200 pounds (100 kg). Maximum muzzle velocity was 800 feet (250 meters) per second. Range could be reduced by releasing less compressed air from the reservoir. Ten shells per gun were carried on board, and 15 shells were fired in 16 minutes 50 seconds during an 1889 test. The shells employed an electrical fuze which could be either set to explode on contact or delayed to explode underwater. From Wikipedia.
