Plenty. In my second post there's a post about plastic armour that will help.
Just to save time - could you point me to the exact bit of that Post ?
I have checked back to it - and all I see ( and have seen it before ) is a Bovington Tank Museum Post about a vehicle with a Pill Box on top.
The point being - the Pill Box.
Not that it is moved on a lorry quickly to where it is needed.
