Level or rank (5)
I believe this is a double definition.
'level' is the first definition.
(I've seen this in another clue)
'rank' is the second definition.
(I know that echelon is a type of rank)
(Other definitions for echelon that I've seen before include "Rank - status" , "Staggering display of military" , "Level or rank in a group" , "Offset-lines formation" , "Echo Len (anag.)" .)
This clue is a double definition.
'level' is the first definition.
(I know that level can be written as grade)
'rank' is the second definition.
(I know that rank can be written as grade)
(Other definitions for grade that I've seen before include "Particular level of rank, quality, etc" , "School mark" , "one of the entertainment moguls" , "Degree" , "Rank or status" .)
