No electrical engineer here but a tank acts as its own ground , tank radios are shielded and insulated , [ so are the radio trucks ] , whatever rf hits the tank is reflected and/or dispersed but recieved by the antenna . A free floating non grounded hunk of metal might cause more problems than its worth as far as the truck vehicle construction goes , weight /economy/material availability etc. Like I said far , far from an expert here but I did stay at a Holiday Inn once …

Tim your blast center is the bomb (sorry had to) 
Enjoying the progress and looking frwrd to the radio room floor debris you’ll be adding.

Looking good Tim and it’s building up really nicely. You are doing a great job with replicating the damage and how it would be. Painstaking work, but it will be worth it

Thanks guys, I’ve no idea if it resolves the question about radio reception/transmission but these trucks had two 8 metre tall hand-cranked telescoping aerials, one on each rear corner. Presumably that meant they had to park every time to send/receive (?) Whatever the reality, how does this look?
If nothing else it should augment the blast effect. But if the consensus is negative it’ll just have to go topless…no rack…I’m sure we’ve all been there…

Looks f 'ed up to me , metal/wood , you’re only gonna find out after it’s built , someone with have photos of it . For my money it’s a go just as it is , beautiful work/destruction Tim !!!

I think it looks great. Wonder about some bit of window frame on the right side, remnants of the telescoping antenna fixture on the right rear. Would the left rear wheel tub remain that way or still to do some denting or other damage?

Thanks guys, that’s 2-0 which is encouraging - it may be subject to some reduction, depends how it looks nearer the finish.
Yep Jack all of that’s to come, with way more debris in (eg some u/s radios) and around the truck. The whole rear especially the left quarter hasn’t entirely disintegrated in my mind yet.

It looks great Tim… but there’s a but …
Before you go down the rabbit hole of destruction… Look at it now and see how the destruction looks and the explosive effect and what caused it … an AP would be through and through in reality on that type of vehicle … so you’d be talking tank or Arty HE and penetrating then exploding from within. What would any secondary explosions come from ? A tank you’d be looking at rounds cooking off and exploding and adding to the mayhem, on this truck …? Maybe 2 or 3 benz jerry cans of fuel, the fuel tank itself ? That would probably lead to a totally burnt out hulk once the fire took hold … just my thoughts …

Thanks John – well, way back in post # 42 I likewise pondered…
“And another gratefully received suggestion came from SamS over lunch last week, narrowing down the destroying projectile to an HE tank round. Pondering the effect of that on a seemingly all-wood planked cabin, I have a T-70 that survived the Kursk dios of yesteryear that’s still up to the job – it’s 45mm canon is probably enough for the kind of damage I’m thinking about (including fire), a 76mm or heavier likely too much.”
And yep I’m still mulling over whether it burned out – 2 fuel tanks were slung under the rear chassis. I think if the wreckage/debris looks OK just scorched, I’ll declare that the fuel tanks were nearly empty. Otherwise, I’ll declare that the rear half was well alight just before a torrential downpour extinguished it. As Tommy Cooper used to say, jussliethat 
The perp…
