When I was in Iraq...we saw ALOT of DPV's, but not as much as humvees. Humvees are still the workhorses for the US military. There are talks of replacing the Humvee with the DPV but there is one small problem....MONEY!
The Use of "Light Jeeps" is discouraged
The FAV and Paratrooper jeeps are not particularly realistic. Most modern armies use Hummer class vehicles as troop transports. Use the Light Jeeps sparingly.
