Unity's free assets licence?

I’m wondering if I can use Unity’s free assets for commercial use, and I can’t find any licence information. Specifically the Stealth project asset. I’d like to know if I can use a sound or texture or two from it?

Thanks.

You can use the assets in just about any way you want in any kind of unity project.

You can not however use pro assets you got from a 30 day trial commercially.
