Another vehicle that is not in any of the canon equipment lists for the V1 and V2 versions of the game would be the TH-400 armored car that Germany produced. They were ready for production in 1996 and thus would have been part of the equipment of the German Army, especially with the war already in progress between the Soviets and China.
As such they would not only be great vehicles to "obtain" from the Germans, they would most likely have been part of the re-equipment of the 278th after they lost most of their equipment on the way over, as well as other of the Cav regiments.
Its a 6x6 mounting a 105mm gun that can fire the full range of NATO ammo. Its armor is only good against small arms and the 7.62mm MG but that cannon more than makes up for it.
Could be used as either an alternative to the LAV-25 or the LAV-75 for die rolls for initial eqiupment but keep in mind it only has a crew of 4.
http://www.pmulcahy.com/wheeled_lcv/german_wlcv.htm has details on it - there are also two other variants that could be used but in 1996 in reality the TH-200 and TH-800 were only in the design stages so the TH-400 would be the better bet for play.
