A Soldier without a metaphorical Heart; a goon. Origins in the Wizard of Oz character of the same name tied with the reality of the shooting of unarmed college students by the Ohio National Guard during the Kent State shootings; Coined in this alloy by Neil Young in the song 'Ohio:'
"Tin soldiers and Nixon coming, We're finally on our own. This summer I hear the drumming. Four dead in Ohio."
