I would guess FasterThanYou refers to sniping people out of tanks when he says there's a glitch to kill people in tanks while on foot, and from the sound of it (and my being unaware of other method) that AzraelX is referring to as well
That is what he's talking about. He only knows about it because it's been said on the forums. He doesn't have any in-game experience.
That is not what I am talking about. My methods are legitimate, as already mentioned. The kind of methods he states will result in him killing me 20 times before I can kill him once, as already mentioned. I will stand on the ground, 10 feet away from him, and destroy his tank.
The only people who think tanks are invincible or even especially difficult to destroy are the forum warriors who spend more time talking about tanks than they do actually fighting them. The people like FasterThanYou who just talk sh*t on the forum and can't back it up in-game, because they have no actual skill or experience to speak of.
In reality, it's harder to destroy a Police Riot than it is to destroy a tank. The only reason you don't hear people crying about it is because they aren't as readily available as tanks, and they don't have a huge ass cannon attached to them. Otherwise, they're a much better defensive vehicle than a tank ever will be.
