Neutron bombs could be used as strategic anti-ballistic missile weapons,[33] or as tactical weapons intended for use against armored forces. The neutron bomb was originally conceived by the U.S. military as a weapon that could stop massed Soviet armored divisions from overrunning allied nations without destroying the infrastructure of the allied nation.[34][35] As the Warsaw Pact tank strength was over twice that of NATO, and Soviet Deep Battle doctrine was likely to be to use this numerical advantage to rapidly sweep across continental Europe if the Cold War ever turned hot, any weapon that could break up their intended mass tank formation deployments and force them to deploy their tanks in a thinner, more easily dividable manner,[36] would aid ground forces in the task of hunting down solitary tanks and firing anti-tank missiles upon them,[37] such as the contemporary M47 Dragon and BGM-71 TOW missiles.
