Initial delivery of a military alert (5,4)

I believe the answer is:

first post

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

'a military alert' is the definition.
I know nothing about this answer so I can't tell whether this works.

'initial delivery' is the wordplay.
'initial' becomes 'first' (similar in meaning).
'delivery' becomes 'post' (I've seen this before).
'first'+'post'='FIRST POST'

'of' acts as a link.

Can you help me to learn more?

(Another definition for first post that I've seen is " Call for retirement".)

I've seen this clue in The Mirror.
