For some reason, THC ran an early showing of one episode last Sunday night, which I stayed up and watched (10PM CDT). It was quite good. It was about artillery.
Ermy showed the differences in the 3 types (cannon, howitzer and mortar), and then fired a whole slew of historical pieces starting with smoothbores in various sizes, a rifled 22-pound Parrot gun, a bronze mortar, modern pieces, ending with the NLOS artillery piece that the US Army will be fielding in 2012. Watching the different historical pieces against 4 water filled barrels lined up in front of each other was very education in demonstrating the effects of the shot. As was the triple canister they fired at massed ranks of - what else? - watermelons.
