Cute berth adjusted for war machine (9)

I believe the answer is:

trebuchet

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

'war machine' is the definition.
The definition suggests a singular noun which matches the answer.

'cute berth adjusted' is the wordplay.
'adjusted' indicates an anagram.
'cute'+'berth'='cuteberth'
'cuteberth' is an anagram of 'TREBUCHET'.

'for' acts as a link.

Can you help me to learn more?

(Other definitions for trebuchet that I've seen before include "onager?" , "Old weapon" , "Medieval siege engine" , "Old slinger" , "Medieval engine of war" .)

I've seen this clue in The Daily Express.
