SNAFU: "Houthis walk up to Saudi/GCC forces and shoot them in their FOB in broad daylight"

SNAFU linked to this video which apparently shows Houthis rebels practically strolling into a Saudi position and shoot the troops--no security or barriers were evident. There was some strung out, loose, barbed wire next to a road down the hill from the position, but that appeared to only strung out to entangle a vehicle, not stop movement on foot.
