Bowmen (7)
I believe the answer is:
archers
'bowmen' is the definition.
('archer' can be a synonym of 'bowman')
This is all the clue.
(Other definitions for archers that I've seen before include "Their sport is the bow and arrow" , "Experts with bow and arrow" , "old soldiers?" , "Her cars, oddly, use bows and arrows" , "Old combatants" .)
