I like it, but a lot of the "results" are bullshit.
Like the viking & samurai, the samurai had no weapons that could do much damage. The katana and naginata are worthless against viking mail, the kanebo was a very rare sight on the Japanese battlefield due it its enormous weight and a viking with a spear would easily best a samurai with one, and the bow can't get past the viking shield. Everything the viking had would easily pierce samurai armor which had a hard time standing up to a katana. A warrior trained mostly in peace-time vs a warrior who has been fighting wars since he was a boy, full-time warrior/pillager would win the day.
The Pirate had nothing that could effect the knight. The blunderbuss only had a few rounds go through just the plate, not counting the mail and cotton (padding) that would be under it and the shield that would be in front of it. Plus they gave the edge to the grenado when it didn't effect the armor but the morning star crushed the skull of its target.
I have yet to figure out why they use artillery like the ballista and scorpion that require a 3 or 4 man crew for a 1 v 1 battle. The Centurion thing was quite BS. Roman soldiers carried 2 pila, a gladius, and the scutum (shield) into battle. The pila were thrown (and only thrown, the soft metal shafts would bend on impact to render whatever they hit unuable so they would be utterly worthless as a melee weapon) before the gladius was drawn and used primarily to stab with the shield raised. A legionaire without a shield is like a Spartan without a shield, worthless to his army.
They pulled the same nonsense with Alexander, whose armor they forgot to test. They also seemed to forget he practiced MMA (I forgot what it was called) because in the battle scene Atilla schooled him when they were without weapons.
I am wondering what they were smoking when they decided on what Schustaffel weaposn to test. They forgot about the MP40, Mauser, STG44, FG42, Gewer 43 and many more weapons the Nazi army used. Despite that though, the Nazi guns were still better than the Vietcong ones.
And in the Jesse James vs Al Capone one, they really had to be drunk. Testing a grenade against a rifle, a sub-machine gun vs a 6 shooter, and giving the edge to a switchblade over a bowie knife?
