State backing leads to new guns for unconventional way of fighting
I believe the answer is:
kung fu
'way of fighting' is the definition.
'kung fu' can be an answer for 'fighting' (I've seen this before). I am unsure of the 'way of' bit.
'state backing leads to new guns for unconventional' is the wordplay.
'state' becomes 'uk' (UK is an example**).
'backing' shows that the letters should be reversed in order.
'leads to' says to take the initial letters.
The initial letters of 'new guns for unconventional' is 'ngfu'.
'uk' in reverse letter order is 'ku'.
'ku'+'ngfu'='KUNG FU'
Can you help me to learn more?
(Other definitions for kung fu that I've seen before include "Chinese form of unarmed combat, was a TV serial" , "Unarmed Chinese martial art" , "'A Chinese martial art (4,2)'" , "fighting" , "Chinese type of karate" .)
