Sometimes all the experience and training in the world will not protect you. Sometimes luck is not on your side and even the top mercenaries in the world have nothing against luck. Sometimes someone can pick up a gun and manage to take out a few people.
There are four ways that this trope is in effect:
- Blind Luck: Someone with little to no training picks up a gun, fires and kills someone who is far better trained. Similar to Accidental Aiming Skills.
- Superior Tactics: The inexperienced use tactics that the elites were not prepared for. They may not be the best but the elites can be surprised. Usually, this would be a Combat Pragmatist.
- Cheap Shot: A Dirty Coward shoots the experienced in the back. Falling under In the Back or other cowardly moves.
- Non Fatal: The non-lethal variety. Sometimes, a new guy in chess can put someone with practice in checkmate.
Note: Cheating does not count because unlike just being normally inexperienced, cheating means that there are rules being broken and no skilled person can really beat a cheater.
Different from The World's Expert on Getting Killed because that trope is about an expert on a subject being killed by someone/something they are knowledgeable about. This trope is about different levels of training between opponents.
This is mostly a Death Trope, so be warned of unmarked spoilers.
- JoJo's Bizarre Adventure: In Stardust Crusaders, Jotaro faces off against Telence T. D'Arby, a highly skilled pro video gamer, in a baseball video game, despite having never played any video game before. He predictably bungles up most of the first round... until he finally says that he's "gotten the hang of it" and scores a home run, then proceeds to prove that it wasn't blind luck, just ridiculously fast rate of learning. It's only when Telence starts cheating with his mind-reading Stand that Jotaro starts cheating himself (via having his grandfather Joseph surreptitiously hijack the controller).
- Watchmen: Former superhero Hollis Mason (Nite Owl I) is killed by a gang of street thugs who over power him. Justified because its one against many and he is much older. But he still puts up a good fight.
- Robin Series: Edmund Dorrance, a Blind Weaponmaster who is skilled enough to give Lady Shiva a fun fight, is defeated in a fight by Tim while he's still in training due to Tim's meticulous planning. Tim was also careful not to run in, only approaching Dorrance after he had already fought and beat to death a more impulsive attacker.
- Cars 3: Non race car Cruz Ramirez switches out with Lighting McQueen and is able to win her first race against a number of experienced racers.

- Gladiator: Invoked. Commodus stabs Maximus before the fight to ensure his victory (thus making it seem like the weaker fighter would win). However, Maximus is strong enough to kill Commodus before succumbing to his wound.
- Star Wars: In the context of A New Hope with the Informed Ability of Stormtroopers, Luke is surprisingly able to take them down. Not as surprising in later films.
- The Professional: Formidable badass Leon is killed when Stansfield cowardly shoots him in the back of the head.

- The Terminator: Sarah Connor is able to beat an unstoppable death machine without any real training.
- Logan: Wolverine gets his ass kicked and eventually killed by X-24, his perfect clone. While X-24 is a perfect clone, he doesn't have the experience that Logan has.
- Green Room: Pat and Amber are able to kill a few Neo-Nazis without any 'real' combat experience. Pat went paintballing and used his tactic of rushing his opponents for that against the neo-nazis.
- Savages: Pacist turned badass Ben is able to kill numerous cartel soldiers only about two days after learning how to shoot properly.
- The Wheel of Time: The greatest Master Swordsman ever to live — an Empowered Badass Normal, veteran of 10 000 combats, who once defeated ten men simultaneously — lost only one fight, to a farmer with a quarterstaff.

- Breaking Bad: Walter White is able to scary veteran cartel member Tuco Salamanca into working with him despite being a mere high school teacher.
- The Two Ronnies: Played for laughs in one sketch where Ronnie Corbett's character, a squash champion, is incensed that Ronnie Barker's character, a newbie so clueless he can't even get the name of the game right, has effortlessly beaten him.
- Call of Duty: A non-lethal variation. In basic training, the player (usually the new guy) can outshoot a lot of guys practicing just because it's a player.
- Pokémon: While VERY unlikely, the player can be beaten by someone younger than them.
- Until Dawn: A group of college students are able to kill numerous Wendigos with minimal knowledge in survival.
- Most online shooters will have this but mostly from either luck in a one on one gunfight or because someone is sitting in a corner.

- Battlefield Friends: The N00b, of all characters, is the one who is able to kill the 100 Colonel. In fact, it's the only time the 100 Colonel is shown dying on screen.
- Avatar: The Last Airbender: Played with. Aang first runs into Toph in an earthbender fighting competition while he's looking for someone to teach him earthbending. He uses airbending and beats her. However, neither knew the others skillset but both were the best, so whoever won would have been this trope. In the sequel series, Toph can now dodge airbending.
- ''The NVA and Viet Cong in the Vietnam War were able to keep the better armed forces of the US at bay and eventually causing them to retreat due their knowledge and use of the enviroment.
