I caught a newsfeed story about the US Army changing the name of its ultralight Ground Mobility Vehicle which was a name used by SOFCOM for a heavy HMMWV fighting vehicle.
It seems the Army wants something to move paratroopers et al from a landing zone more quickly to the objective than by the Mk II Leather Personnel Carrier, Black, Lace-Up. The links mentioned Polaris has a four-seat side-by-side utility vehicle already in limited service. I checked the link and wonder of wonders, the MRZR is just about the same size and performance as a WWII Jeep. This is more powerful, but it is interesting how the needs of the soldier have perpetuated and manifested almost the same way twice.
