Have you seen the pictures of the "Carpet bombing" of the Hanoi rail yards after Linebacker II? Overlapping craters, a very few craters outside the rail yards.
Todays B-52H is much more accurate than the B-52D and -Gs of 1972-73. Given an area target, such as a rail yard, or the "training camp" in the news today, yea, I'd send in the Buffs and the Bones.
Buffs and Bones can also deliver multiple precision guided munitions on a single pass.
The idea is to hit the target(s).
