Military Jeeps

Despite the proven success of the Hum-vee (short for M998 High-Mobility Multi-Purpose Wheeled Vehicle, aka. HMMWV or Hummer in civilian form) in combat, I believe that the complete discontinuation of the Jeep from the US inventory in favor of the Hum-vee was premature. The Hum-vee serves many functions very well but not all.
Urban combat has dictated that vehicles must be either fast and manuverable or survivable.

Due to its size, the Hum-vee is not capable of great manuverability thus it is a sitting duck in the alleys of many 3rd world cities. As strong as they are, Hum-vees were unable to survive somali RPG ambushes despite its additional armor. Thus if a vehicle is large and not manuverable it should therefore compenstate w/ survivability.That role is better relegated to the Bradley IFV

At the opposite spectrum is the light, fast and manuverable vehicle that can be used for recon and patrol. The vehicle best suited for this role is the Jeep. If ambushed it can easily reverse direction and J-turn or advance and complete a 180 bootleg turn. (note: I am assuming that the Jeep IFS suspension has been modified to avoid rollover) Thus, it can escape without being hindered by its size. It could evade through the small alleyways of a 3rd world city. Direct action against the enemy can be left to the Bradley IFV.

Future design for a Marine Fast Attack Vehicle
Daimler/Chrysler-Jeep TJ, has potential for conversion to military use as an FAV for recon, escort or patrol. Not a bad deal for $12,000-22,000 USD.
