"I'm not sure it's the sort of thing that the firing range would be much use for," he says, as he purses his lips in thought, then takes a slow drag from his cigarette and watches the smoke. "Not even sure it can be offensive. How do you quiet something offensively?"

"If I wanted to try that, I'd really have to test it on things that make sound," he says, that expression turning to a frown. If he ever wants to use it in actual combat he'll need to either test it on people first, or test it on people there at the time, and both come with downsides, don't they. But there are other types of things that make sound, and also, in truth, he's not even sure he has to stay so limited. If he can drop sound waves to a standstill, can he do that with other types of waves?

... Yeah, he's going to need some science help.
