10 Crazy In-Universe Rules MCU Characters Must Follow

One of the defining traits of the Wakandan army is that they're basically the only modern army around the world that doesn't use guns.

Despite their technologically advanced nature, they eschew traditional projectile weapons entirely.

This is in large part due to their vibranium-laced arsenal - namely their spears and gauntlets - producing sonic blasts capable of causing massive amounts of damage.
