I thought the neutron bomb has the radiation and the fallout (that's how it kills) but does not have the explosive power to destroy buildings. It wipes a city clean of life but lets the infrastructure remain intact.

It has the radiation, but the high speed neutrons penetrate deeper and kill, but it doesn't have the fallout like a conventional nuke does. The blast is a lot smaller, and it is detonated a lot higher. There is always going to be some fallout, but it doesn't kick up nearly as much. It is also really good for armor, and if you were in a M1A2 the depleted uranium hull can actually ADD to the neutron radiation, not the place to be if one of those cooks off.
