Iron Man is vulnerable in the eyes and I believe Sabretooth can be overloaded since he has no adamantium skeleton.If a tank round hit Wolverine or let's say anything nearly equivalent to a .50 caliber machine gun it could provce fatal. Dude still has arteries that aren't protected by his skeleton. Not to mention his eyes or dick getting taken out. Like to see him grow those back. We haven't seen him grow anything back in the movies but flesh wounds. He has shown no signs of regeneration like Deadpool in the comics or Piccolo/Cell in DBZ.
With unlimited ammo, Robo and T-800 could probably solo, given enough time.
Sabretooth's non-metal laced skeleton only means his bones can be broken, though by the damage he's taken, those bones are far more durable than regular human bone matter. He can still heal broken bones though.
A tank round or .50 cal will not prove fatal to Wolverine. He can heal from bullets entering his skull (see Origins), so tanks shells and .50 cals would only tear off chunks of flesh, which he'll heal from.
He has grown back large portions of flesh when Phoenix was disentigrating him away, there's no reason to believe his eyes or dick wouldn't grow back, as it's all just flesh.
