Strictly speaking they don't, since no plasma weapons exist today. ... The electromagnetic confinement field would keep the plasma coherent on its trajectory, so that it's still hot enough to cause damage when it arrives to the target.

Can plasma be a weapon?

A plasma cannon (also called an electrothermal accelerator) is an experimental projectile weapon, which accelerates a projectile by means of a plasma discharge between electrodes at the rear of the barrel, generating a rapid increase in pressure.

Are plasma bullets possible?

The plasma bullets are created by a “plasma pencil,” which is a pulsed plasma source that the researchers previously developed. ... When the gas ignited between the electrodes, it launched a plasma plume through the hole of the outer electrode up to 5 cm into the air.
