Halflings

[Finrod]

Tolkiens halflings are plenty warlike when they need to be. Bilbo had an ancestor who invented the game of golf by knocking the head off a goblin king with a club and in the Scouring of the Shire the halflings had little trouble defeating Sauramons minions once they were organised.

and Merry stabbing the Lord of the Nazgul, and Pippin killing the Hill Troll, and Sam in Shelob's lair, (even Fatty Bolger before the scouring of the shire)...They were very warlike at times.
