Zngyelse The lede says that the base is also known as Zngyelse  Who calls it this and why  It certainly looks like a confused misreading of the Russian name  taking the  for  and adding an odd letter e at the end  The ye in the middle would also be an unusual transliteration although understandable  Is there a source behind this alternate name  A Google search shows a lot of web sites that similarly claim this name is also used but just as likely theyre getting it from Wikipedia rather than the reverse  Theres no hint of any such name in the Russianlanguage Wikipedia article unless as I mentioned you misread the Russian name
