Military pageant (6)
I believe the answer is:
tattoo
'military pageant' is the definition.
(I've seen this before)
This is all the clue.
(Other definitions for tattoo that I've seen before include "Military display - needlework!" , "Indelible marks drawn on the skin" , "Military entertainment or skin adornment" , "Pointedly design" , "Example of body art" .)
