These types of vehicles are now widely referred to as "technicals":
> Africa, says [David] Kilcullen, is where the truck got its

> Somalia,” he says, referring to a period in the 1990s, “they

> owned by a guard company, and then eventually to mean a Hilux
> with a heavy weapon mounted on the back.” [1]
