Rush to include revolutionary instructor (7)
I believe the answer is:
teacher
'instructor' is the definition.
(I know that instructor can be written as teacher)
'rush to include revolutionary' is the wordplay.
'rush' becomes 'tear' (tearing is a kind of rushing).
'to include' indicates putting letters inside.
'revolutionary' becomes 'Che' (Che Guevara).
'tear' going around 'che' is 'TEACHER'.
(Other definitions for teacher that I've seen before include "The trainer" , "Lecturer" , "Guide" , "Mentor" , "'Instructor, educator (7)'" .)
