And this gentlemen, is precisely why the most prestigous challenges don't matter that much in this game that mattered in Black Ops 2. I don't know what they were thinking when they decided that specialist weapon kills should go towards kill chain / nuclear.

Not trying to ♥♥♥♥ over your achievement or anything, it's still really hard to do, just not nearly as hard as it was in Black Ops 2.
