WCRA: Nautilus tank

Nautilus is a heavy tank unit in WCRA
This versatile heavy vehicle has three distinct weapons that it utilizes for different purposes. A hefty short-medium range primary weapon to lob mortar shots over barriers and clear out base defenses, a modest machine gun to lay down covering fire and attract the attention of all base defenses and units, and a short-range railgun to vaporize any ground units that get too close.
