ERWs (Enhanced Radiation Weapons, aka 'neutron bombs') are very destructive in themselves, contrary to popular misconceptions. An EHR of, say, 5okiloTon yield would cause approximately the same blast damage as the 10-20 kT Hiroshima and Nagasaki bombs. They would kill biologicals out to a greater distance through radiation effects than those weapons did, but they still are enormously destructive. In general the radiation effects are enhanced about threefold over "conventional" nuclear bombs.
50 kT (not 5oKiloTon)
I probably ought to add that it appears that the US has no EHRs in our inventory and that, most likely, because we have rejected that they are more useful than conventionals bacause they complicate the battlefield situation rather than simplify it.
