Over many tens of thousands of years, human motor skills and reflexes evolved as a response to biological threats, long before any technology made things faster than neural signals could move the muscle tissue. The average response time to a visual stimulus is about three-quarters of a second, or half that for people who are alert. That does not sound like a lot until you take into account other factors, like rocket motors.
A typical anti-tank missile flies at about 250 m/s. This means it will clear about one and a half football fields in the time it takes the human brain to register and respond to a visual signal. It’s a metallic object the size of a bread loaf, jumping football field lengths as fast as you can blink.
Even if you can see it coming, you have no time to react.
You can’t dodge missiles.
