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

'military display' is the definition.
'parade' can be an answer for 'display' (parade is a kind of display). I am not sure about the 'military' bit.

'a padre upset' is the wordplay.
'upset' indicates an anagram.
'a'+'padre'='apadre'
'apadre' anagrammed gives 'PARADE'.

'by' is the link.

Can you help me to learn more?
