Boring, but Practical: The baseball bat may not have been the flashiest weapon (especially compared to the Yakuza's nunchaku), but it was perfectly legal to carry, and pretty effective, too. A smart swing from one of the experts visibly snapped several of a test pig's vertebrae.
Badass Boast: Deadly enforcers on the mean streets of New York.
Your Freedom Fighters Are Our Terrorists: These episodes were never screened in Britain. Funny, that. The fact the IRA are thought of as murderous thugs who are very good at blowing up women and children... well, obviously pernicious Brit propaganda and a slur on brave idealists.
While the IRA did commit acts of terrorism the frequency was greatly exaggerated by British propagandaists; in truth only 36% of those the IRA killed were civilians, compared to the British Army's 51% and the pro-British UDA's 85%.
Badass Boast: Hardline religious extremists who back their beliefs with bullets.
A God Am I: The Oracle of Delphi told him he was the son of a God.

Badass Boast: The warrior king, whose brutal tactics carved out one of the largest empires in history.
Badass Boast: Africa's deadly new breed of high seas hijackers who make millions holdings merchant ships hostage.
Enemy Mine: The ships fishing in the waters of Somalia were a common enemy for people who once fought each other in the Somali Civil War, from fishermen who spent their lives in the water to militiamen who knew guns.
Awesome, but Impractical: Played with via the chariot scythes. They look nice, and tore through two pig carcasses, but was deemed to lack true killing power and lost the edge to the Celt's burda club. However, it still got over 100 kills.
Badass Boast: The precision killer in a massive war machine who forged the largest empire the Middle East has ever seen.
Badass Boast: The ruthless Chinese warmonger who revolutionary "Art of War" led to the massacre of millions.
Which laps into Critical Research Failure as anyone who's read the book knows that he states that war is only meant to be have as a last resort and to obtain the least amount of deaths as possible. Of course, Other Chinese commanders who weren't as humane would use his tactics and kill, literally, millions. Quick trivia quiz: What was the bloodiest(in terms of lost lives) war to occur in the first half of the 1860s? It's not what you probably think.
Badass Boast: The bloodthirsty French emperor whose maniacal dream was to conquer the world.
Bait and Switch: His tactic that earned him the victory at the Battle of Austerlitz: fool the Prussians into thinking he and the Grande Armee were surrendering, luring them onto the hill Napoleon and his men were just on; then, obliterate the present forces when a dense fog overcame the area.
Cheese Eating Surrender Monkey: Averted. Even though he lost, it was a difference of 60 battles out of 5000, the second-closest margin of defeat throughout all three seasons.
The Napoleon: The experts mentioned how 5'6" was normal height for a European man of that time period but he comes off looking like this anyway because he's paired with the freakishly tall Washington and his own taller-than-average bodyguards.
Badass Boast: The daring and deadly French duke who crushed his English enemies and crowned himself king.
Disproportionate Retribution: Edward the Confessor promised William that he would be the next Duke of Normandy. After Edward's death, when William found out that the new duke became the son of Edward's advisor, William felt that he was betrayed and started a campaign against Harold.
Eye Scream: How William used his crossbow to kill Harold.
Underdogs Never Lose: Most of the x-factors were against him and even most of his weapons and tactics were rated lower than his opponent, yet he still came out on top.
World War One: Tried to enlist in this, but was turned down by President Woodrow Wilson; partly due to his advanced age, and partly for political reasons. At least two of his sons fought in it though, with one getting killed.
Vocal Dissonance: His victory cry is notably less energetic and fierce than every other warrior we've seen. This carries over from real life: he was actually a soft-spoken man with a rather posh speech pattern and an oddly-squeaky voice.
Oh Crap: Cited as an actual X-Factor. As powerful as they are, they are still capable of feeling human emotions, like fear. Sure enough, the vampires freeze up, stare, and then retreat upon seeing a comrade get torn to pieces and then eaten.
One-Man Army: A fair fight was considered near 200 zombies vs. 3 vampires because one on one the vampires would win every time thanks to being able to One-Hit Kill zombies thanks to their superior strength. The vampires win.
Pyrrhic Victory: Technically won the fight, but then infection starts to set. Though the experts couldn't decide on rather becoming a Zombie Vampire was this trope or Cursed with Awesome.
Probably the first. The resulting zombie-vampire would still have the vampire's weakness to sunlight but not the brains to avoid it, so would last until it tried to chase something in the dawning day. Final score: double KO.
The Spock: He's definitely the most stoic of the trio, and his measure of a weapon basically boils down to "which one would I rather not be hit with, and which one is less taxing were I to use it for myself?"
The Kirk: While he doesn't get quite as worked up as Geoff, he's definitely more animated than Armand. On top of that, his main role on the judges panel is to bring a more grounded, hands-on perspective to the weapons that the engineer and medic simply aren't as trained for.
