Armed Forces Tournament Finale - S8.E31

On the finale of the Armed Forces Tournament, the four surviving smiths will face off to determine who wins it all. In the first rounds, they're challenged to make military-style weapons out of an old bazooka. After a round of testing more intense than boot camp, the worthiest smiths return home to make the ultimate military weapon--the Ames Cavalry Sword. Which smith will take home the $10,000 and rise to the highest rank of Forged in Fire Armed Forces Tournament champion?
