As Andreas says above, the Radian armored cab that is on the Trumpeter M1083 was seen on vehicles in Iraq in the early days. It was one of many armored cabs that were trialed there, but it was ultimately not selected.
The one selected was the type on their Armored M1078 kit. It was known as the Low Signature Armored Cab (LSAC).
This has been updated to the current one known as the Long-Term Armor Strategy-compliant (LTAS) cab.
The M142 has a similar cab to the LTAS, but it has smaller, more armored windows to counter the effects of the rockets as they are launched.
