I'm afraid I can't agree with your giving this mission an 8, I wish I could, but I can't.
I played it, but I had to restart several times to actually play it through, simply because the boat kept doing a sharp left turn when we got the disembark order, and we ended up being booted out of the boat in open sea and drowning. It did this over and over again, and only worked properly when I was recording a video of the bug...
My first try was running FDF mod, I thought perhaps the mod was causing problems with the scripting in the mission, though I considered that unlikely, so the rest of the times I ran the mission in standard OFP:R, no mods, and the problem still occured. Every time, we got booted out of the boat into the sea. The intro didn't work either, unless the author intended the intro to depict a UH60 landing in the ocean in front of one of the PBRs (crashing into it in the process), then fade to black...
As for the mission itself, I thought it was unusually short.
I moved with the squad up the cliff, cleared the heli-base, which, for such a high value target, was extremely easy to take. Most of it's tents and fortifications were sticking up sideways out of the mountain, I could only fix this by setting the terrain detail to very low. And then, after waiting a short while to sync with the other squad, we moved on Vigny. My squad leader got killed immediately as he reached the top of the hill and exposed himself to all the enemies at once, the rest of the squad members did the same and all got themselves shot too, one at a time. Most of them didn't even get any shots off before they died. Only I and no. 5, the LAW soldier, who was stuck back down near the helipad for some reason, survived. I moved up slowly, popping up to fire, then crouching down again and shifting position, I managed to kill all of the enemies (militia mostly, few Soviets) on the first try, though I was wounded by a grenade close to the end. The battle only lasted a few minutes.
War stories aside, I thought it was buggy. Neither the intro, nor the insertion worked as intended, (though I have no idea why the insertion stuffed up like it did 9 times out of 10) and while the atmosphere was pretty good at times, I'll only give it a 5/10.
