Those are supposedly SEALs.
I don't think that is the ALSV. There is a LSV that seats eight instead...made around the same time as the DPV. This looks like the eight-seater LSV.
The bottom photo is a DPV, evident because the gunner sit in his high rear seat under a rollbar.
The photos show why the LSV idea is falling out of favor. Called Fast Attack Vehicles, these FAVs are great IF you know where the enemy is to attack so you can drive off a helicopter and attack the enemy. But they're torture as long-range Desert Patrol Vehicles, which is why the Green Berets prefer the "Dumvee," which is called "Ground Mobility Vehicle" as the official title, because the Dumvee hauls more and is more "truck" than dune buggy.
