I'm a little stuck... Click here to teach me more about this clue!

'military display' is the definition.
(I've seen this before)

'state stood endlessly' is the wordplay.
'state' becomes 'tat' (I can't justify this - if you can you should believe this answer much more).
'endlessly' means to look at the middle letters (the ends of the words are removed).
The central letters of 'stood' are 'too'.
'tat'+'too'='TATTOO'

'for' is the link.

Can you help me to learn more?

(Other definitions for tattoo that I've seen before include "Indelible decoration on skin" , "Drum signal, display" , "Indelible impression" , "Skin design; mil. display" , "piercing?" .)
