Soldiers shot arrows -- I run inside (8)
I believe the answer is:
warriors
'soldiers' is the definition.
(I've seen this in another clue)
'shot arrows i run inside' is the wordplay.
'shot' indicates an anagram.
'run' becomes 'r' (cricket abbreviation).
'inside' means one lot of letters goes inside another.
'arrows'+'i'='arrowsi'
'arrowsi' is an anagram of 'wariors'.
'wariors' going around 'r' is 'WARRIORS'.
(Other definitions for warriors that I've seen before include "Arrow, sir for the fighting men (8)" , "They're engaged in battle" , "Arrows, sir, for the fighters" , "People experienced in fighting" , "Combatants, soldiers" .)
