Many years ago when tanks had not been fully developed, their only natural predator were jets and helicopters, having superior air priority. After many years of evolution; the tanks have grown one defense over this: the front cannon. Although it take about four tanks to fully corner a tanks food source; the sniper, it can take only one tank to now fend itself from a jet. It isn't guaranteed a tank will live, but this new tanks will show what a more experienced creature can do.
