it’s not. Light only travels at c in a vacuum.

If you really want to be pedantic, c is the notation for the “speed of light in a vacuum”, not just the “speed of light”, which depends on the medium.

Headline says that it can fire at the speed of light though not that it does.

I am being pedantic here, but if the laser travel at the same speed as c in a given medium, then it is going at the speed of light.
