I was in during the transition.
The HMMWV did perform well, but they cost seven times as much as a Jeep when they were initially deployed. I thought that their size was a problem in mountainous terrain (Four strong guys could pick up a jeep and turn it around) but that they cornered a lot better than the Jeeps.
I would like to see these new vehicles take over. They look like their design is more in line with armorial the flooring against mines.
At this point, would those vehicles survive an IED? I think that’s the only practical question here.
