GITS: SAC - "Testation" - On Augmented Vision

In the second episode of Ghost in the Shell: Stand Alone Complex, a dying man's brain is put into a war tank and Public Security Section 9 is tasked with stopping it. Because this tank uses advanced technology, the team finds that their normal tactics are ineffective, and must rely on ever-changing methods to combat the situation. One of the first methods the team tries, however, is having a sniper deliver an armor-piercing round into the target.

That sniper's name is Saito, and while his body is 90% human, he has one eyeball that is 100% mechanical. When it's inactive, it looks like an eyepatch covering the eye, but when he uses it, it flips up to reveal a highly efficient camera lens.

This lens has several augments to it. It can see well over 2 kilometers away. It can be used to apply filters over one's field of vision; for example, Saito uses it to overlay a topographic map in order to estimate slopes from far away. This gives unprecedented depth perception at long range. Sensors within the eye also display wind velocity. Finally, Saito can use satellite connections to lock-on to a target.
