Yup, that's a WWII-era Army jeep. Built in 1944. The Ford GPW!!!!!!!!!

Ford built more than 300,000 GPW military jeeps in all, which amounted to roughly half of all jeeps built for WWII. According to the Lyon Air Museum in Santa Ana, California, the name stands for, G: Government contract, P: 80-inch wheelbase, and W: Willys design.
