What anime is that epic headshot from?

[XtortionBear]

I remember seeing a video within the past couple months on Youtube that was a from a futuristic anime in which a man in a spacesuit takes a bazooka-like weapon out and shoots through a spacecraft's windshield decapitating a woman (likely the antagonist). I cannot find this video anymore, and I was wondering if anyone knows what anime this is from. Couple friends of mine at work were wondering as they're anime buffs and they'd never heard of that scene before.

Thanks in advance.
