Although slow and expensive, railgun tanks can deal massive damage from long distance. It is good vs mid-ranged units, but can tear apart any units with ease when sufficient number of them are gathered in a base with defense grid support. The only way to counter these high-tech tanks are with bombing run on the defense grid, followed by suicide runs of fast units like hammerheads and hellfires with mixed army following closely behind.
