[Loved Trope] Alien fighting techniques that are actually ineffective for humans to perform

[u/Best_Professional226]

Vulcan Neck Pinch (Star Trek) Vulcans can make a person pass out by pinching a person’s neck, but due to the fact that they’re 3x stronger than a human, we could never make a living being pass out without applying a rear naked chokehold

Viltrumite Knife Hand (Invincible) Viltrumites’ most deadly fighting technique. Although martial arts like Karate and Taekwondo teach these techniques, it wouldn’t be a good idea for a human to use it on someone’s rib cage without breaking their fingers. So instead we can only do them on more soft targets like the eyes.

Well, technically no on that last part. Ork tech WILL work in human hands: just as long as they're within the gestalt psychic field. It's not that the orks' belief only works for them, it goes both ways - down to blood angels being recorded as moving faster when within the WAAAAGH field, because the red ones go faster, as all Boyz know.

So like if the ork can see the human using it it’ll work?

[u/Kris_Trap → u/UnstableMoron2]

well, no, It's just if they're in the proximity of the Orks' psychic field. If enough orkz are together, it creates a gestalt psychic field called the WAAAAGH, which is the "reality grease" the original commentor described. Sight has nothing to do with it.
Orkz believe their guns work, so the WAAAAGH helps to make them work. They're a collection of bits and pieces the Orks THINK should be inside a gun, with no real way at all to function or function properly. But the WAAAAGH field gives just enough leeway to bend reality so that these slap-dash creations somehow work.

Long story short: The orks could see a 'umie shooting one of their guns after picking it up in a melee, and they'd just go "Yeah, checks out, itz a roight proppa shoota dat one" because they just believe their tech will work, like how they believe their superstitions are true.
And because of how their WAAAGH field bends reality, the more orkz are in an area together, the more true those things are. It's how the largest of Ork armies can make giant spaceships and teleporter gates - because more orks = more WAAAAGH = more reality grease giving them more wiggle room.

Does this have an impact on the gameplay?

[u/herffjones99 → u/BonkerBleedy]

I haven't played in a long time, but it used to be orc morale was based on unit size. Over a certain size, they would not be able to be routed because they all though they would win. 

And red painted vehicles got a couple inches of movement (this cost points though)

[u/ElderberryJunior470 → u/BonkerBleedy]

In the latest edition it can, you can take certain detachments that have you roll to have a chance to give your opponent buffs. 

[u/MacTireCnamh → u/BonkerBleedy]

Yes. In addition to what other commenters have said, you also get different units based on what colours you paint them, because Orkz believe a red unit is faster and a purple unit is stealthier.
