The W70-3 was a modified version of the W70 and one of the first warheads to be battlefield-ready with an "enhanced radiation" (i.e. neutron bomb

) feature. It had an explosive yield of about 1 kt., was manufactured during 1981-83, and was retired by 1992; 380 were built. Note that using the explosive yield of a neutron weapon to measure its destructive power can be deceptive: most of the injuries inflicted by a neutron weapon are caused by its intense pulse

In physics, a pulse is a single disturbance that moves through a medium from one point to the next point.-Pulse Reflection:Consider a pulse moving through a medium - perhaps through a rope or a slinky. When the pulse reaches the end of that medium, what happens to it depends on whether the medium...

the W-70 ... is not even remotely a "neutron bomb." Instead of being the type of weapon that, in the popular mind, "kills people and spares buildings" it is one that both kills and physically destroys on a massive scale. The W-70 is not a discriminate weapon, like the neutron bomb — which, incidentally, should be considered a weapon that "kills enemy personnel while sparing the physical fabric of the attacked populace, and even the populace too."http://findarticles.com/p/articles/mi_m1571/is_29_15/ai_55426724/pg_2
