Personnel use? I dont think Nick Fury is the kind of person to just hand out helecopters full of acid to anyone that asks him for it. And why would you want to kill him? Are you really that obsessed with your mission that your willing to kill the person that ordered you to do itin the first place?
Ok, fine, whatever, lets say that actually makes sense, and you get two helecopters full of acid. More acid isn't gonna help, as the first batch was enough to reduce him to a skeleton. Thats happened to him before, and he's healed from it in just a few minutes. And you still haven't said what you plan to do after that. Trap him in a cage? he cuts through it. Adamantium cage? Adamantium>adamantium, correct? So I just don't see option 1 working. As for option two, ok, fine whatever, I'll cut you a break. Lets say that you successfully befriend Wolverine, and get him drunk. As I said before, due to his healing factor, he sobers up FAST. And even if you can shoot him before that happenes, Wolverine gets shot at all the time, and I don't remember that ever knocking him out. Yeah it happened in the second movie, but that was a movie. So I don't see that one working either.
I'll only say this once more, if Nick Fury gets in the way of my mission he won't be there to congratulate me afterwards. Lets just put it that way.
Makes sense to me.

I never said anything about a cage. At all. And I never will. I used trucks, boats, acid, bullets. Those are my tools.
About coming back from a skeleton. It is a little ridiculous, but apparently Wolvering has regened from a skeleton before. Even if such a thing were possible . . . . here's what I would do. After dumping the acid onto him (and the others), I would then place the skeleton (which can miraculously bring back living tissue in a way that reminds me of the Japanese anime Guyver) in a vat of acid. If the skeleton is suspended in Acid, how can wolvie do his magic and come back? What say you to that?

About sobering up—I wouldn’t give him the time to. I simply need him to pass out. I trust that wolverine will want to get drunk because he strikes me as that type. Haunted by his past. Wants to bury it. He knows that he needs to drink more than the average joe, and he’ll do it. I’d give him a bottle of sake to drink on his long walk back to his room. I would befriend him, then encourage him to drink up, dear, dear wolvie. Drink up. Your past is haunted with the ghosts of your victims. You’ve got blood on your claws. Here, take another sip.
As far as the bullets not knocking him out um . . . I’m no brain surgeon, but I’m pretty sure a bullet to certain parts of the brain would cause one to lose consciousness . . at the least.
