The original deuce and a half trucks were designed during Old Terra's Global War, also known as the Second World War, to simplify the action of moving supplies to troops in the field. The originals deuces and their descendents served in every war until the creation of the Star League. The new Star League commissioned a series of vehicles that could carry larger loads for the modern war against the Old Periphery and the deuce and a half faded out of major use in the Star League states.
         The old deuces remained in use by civilian concerns, especially since they were cheap to purchase at military surplus auctions, but the Star League standard survived the end of the Star League, and for a time even its reformation. The FedCom Civil War reintroduced the deuce and a half to Davion forces though. With mounting losses and an inability to acquire new transports from a military-industrial complex controlled by Katherine Steiner-Davion, those loyal to Victor Steiner-Davion were forced to draft civilian vehicles, many of them actual deuces the Federation had used before the Star League standard was established.
         The deuce and a half trucks worked so well that many commands continued to use them after the Civil War ended. The Jihad further forced commands to dip into the "civilian" market and once again the deuce and a half saw expanded use. By the end of the Jihad, the deuce and a half had become such a common sight in the Federation military, that its use quickly began to proliferate throughout the Federation Expanse. Built by hundreds of companies for civilian and military use alike, the deuce and a half is a cheap way to transport small amounts of cargo wherever it needs to go.
