A sniper that can be equipped with both androids and ravens, maybe marine too...
When it detects something, the red dot keeps flashing, there's no lasers but maybe scope will detect.
At shooting, it will become black and flash slowly red, then it will be red back.
I couldn't put the image, because the resolution and graphics are very hight, (error message: Your images may only be up to 1200 pixels wide)
Anyways, here's the link.
