FUN FACT a lot of russian equipment follow nature based naming conventions a good example is russian artillery pieces or related weaponry typically being named after flowers Hyacinths, peonies,

and carnations etc like the pion(peony) malva (mallow? flower or the flower thereof) Tyulpan (tulipan) etc

the orezhnik very much follows this principle it's name meaning hazel like the nut in this case referring to the flowers of the tree from which the nut comes

as they are similar to the trails of light from the orezhnik
