In my comment above I provided a link to the provided source Berhow 2005 p 32 This can be seen on Google Books There is no mention of neutron bombs on this page You did not and can not demonstrate the citation was correct because the citation is not correct I have not removed material due to typos and have not stated an intention to remove material due to typos In each case where I have removed material or stated my intention to remove material I have done so because no reference was provided or because a reference was provided which failed verification Currently the claim that The W66 is widely reported as the first neutron bomb although any differences compared to the W50 other than yield are unclear has failed verification If no reliable source is provided from this claim I will remove it from the article
