From a command and control standpoint I could see how the powers that be wouldn't want hundreds of these things roaming the battlefield.
But think of the possibilities. Speed, mobility, stealth, surprise ... in a platform that can be tailored for the mission. Cheap too!
I'd take one of these over a Hummer or a 151 anyday.
Thanks for the "zoom zoom" link. Interesting how they pulled some the FAVs out of mothballs after Sept.11 and refurbed them.
