Sniper vs Armoured vehicle.

You should read the threads. I doubt that you have a new argument, nor even a new response to an old argument. Ever been in a tank? If you have access to one, even a static museum piece? Go sit in it, if you're allowed to. Can't see out, can you? Neither could the crew. They had to stick their head out to see anything. Heads make good targets. If you can't hit a head at 50 meters, you should practice more.
A tank alone is easy meat. You can jump on the back and piss in the carbuertor if there is no one watching for that ( A line from the movie "Sahara"). That is why tanks are always used in mass.
