> Mortars are a hell of a lot more lethal any consumer firework.

Well, some mortars are. Other mortars are consumer fireworks.

It's almost like, in the interest of clarity, we should use specific, non-overly-broad words that can't be misinterpreted. The use of the word "mortar" here is clearly causing problems, so how about "aerial firework" and "combat mortar"?

Good point, I wasn't thinking of actual military mortars. But I think "mortar" often means consumer firework in modern parlance.

I think there might be a lot of people here (my self included) that literally didn't know that about fireworks in modern parlance. It's because talking about fireworks just doesn't ever come up in my life. But I think "mortar" is commonly known as a military kind of weapon even if you know nothing about fireworks.

I was unaware of that terminology applied to fireworks. Good to know!
