Call for grand parades, but no soldiers (4)
I believe the answer is:
page
'call for' is the definition.
(to page is to call with a pager)
I don't understand the rest of the clue.
Can you help me to learn more?
(Other definitions for page that I've seen before include "Errand boy at hotel, club etc" , "Court attendant" , "Call out the name of" , "errand-boy" , "Young attendant for part of a book" .)
