One of my weird current fascinations is the “Truck-APC”, for lack of a better word. This is an armored personnel carrier built on the platform of an existing truck. One of the first widespread truck-APCs was the BTR-152.
Since that ZiS-151 with armor rolled across Red Square, there have been many, many, many vehicles of that nature. It’s undoubtedly easier for smaller and/or lower budget firms to make something where much of the “heavy lifting” has already been done by someone else than a clean-sheet design. I’d have to say one of the more unusual (or my favorite) truck-APCs is the kind where the front part is just an uparmored pickup truck, but an “APC-like” troop compartment is placed in the bed.
A reason I think the truck-APC has come to prominence in my mind is the kind of books I read. The truck-APC is more suitable for security forces than it is for higher-end armies squaring off against IFVs. Guess what the small-unit action-adventure novel protagonist is more likely to face?
