I'm working on a small dio for the Overlord campaign using the Tamiya Bren carrier, and some of the barricades in the old Tamiya barricade kit. My idea is to show two barricades still standing, with a blown up one in between. To show that the middle one was removed to allow vehicles through.

Any ideas on showing the destroyed one? I can't find any pictures online of these things either complete or destroyed.

A lot of the barriers were made from angle iron, so any that are demoloshed/removed would be simple to portray with a few bits of Evergreen girder. I watched a TV programme the other night about the invasion, and was reminded of something useful here. As quite a few patches of sand had soft clay under them a device known as a 'carpet' was used. laid by a Sherman or Churchill. This was a length of fabric as wide as the tank,reinforced with crosswise battens, and laid across the sand end-to-end. How about that for an idea - laid between the barriers with the carrier moving along it........

Can't remember what movie or documentary I saw but I seem to recall that on the angle iron obstacles like the ones in the Tamiya kit, they simply placed a small charge where the three girders intersected and blew the welds. Then you have three pieces just lying on the sand, easy for tanks to roll over.
Of course when the beach was secured the engineers simply used torches to cut up any of the remaining ostacles.
Maybe you can show the two obstacles with a tank passing through the gap and a pile of girders near where the third obstacle would be located.

It was called a "Bobbin". Usually it was a Churchill equipped with a giant spool, which rolled out a 110-yard-long carpet of coir - a coarse material made from the husks of coconuts. This carpet, stiffened by bamboo rods, was unrolled in front of the advancing Bobbin. The carpet was first pulled down from the spool and guided by hand until it caught under the tank treads (one of those time you better watch where your fingers are). The th eforward movement of the tank pulled down more of the carpet. The spool could be lowered when the tank was on level ground. What I find interesting is that it still has its 290mm mortar 57mm gun (the 290mm mortar was on the Churchills that were modified into the Armored Vehicle Royal Engineers - AVRE - that were further modified into the Bobbin tanks). Why that is interesting is because to hold the "spool" up was an "N" shaped frame on either side of the tank and from pictures I've seen - especially with the 57mm gun - it would appear to be moot to try and use it. Now when the Bobbin was lowered, there wasn't any problem firing forward (though the muzzle blast probaly wasn't good for the material. And even when lowered, it still appears that the gun can't traverse more than a few degrees.
