I believe the answer is:

manoeuvres

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

'moves across battlefield' is the definition.
'manoeuvres' can be an answer for 'moves' (manoeuvring is a kind of moving). I'm unsure of the 'across battlefield' bit.

'me a nervous wreck' is the wordplay.
'wreck' indicates an anagram.
'me'+'a'+'nervous'='meanervous'
'meanervous' is an anagram of 'MANOEUVRES'.

'making' acts as a link.

Can you help me to learn more?

(Other definitions for manoeuvres that I've seen before include "Soldier works" , "training exercise" .)

I've seen this clue in The Guardian.
