We are Warriors of the Shire!?

There is no reason to suggest that, given Frodo and Co. were plucked from the quiet Shire, and gradually transformed into warriors on their fraught with danger quests, that other Hobbits from the Shire could not do likewise. Hobbits, if trained with the appropriate tools and experience, could have played a significant part in the war against Sauron if called upon by Gondor. They may be of no use against trolls and Nazgul, but they could have been employed as spies of the lands, as able archers, and as messengers.
