Fighters are the most common meatshields. It is common knowledge that they're good. But are they? Yes, definitely, and there is absolutely nothing better than fighters for the cost-effectiveness ratio. Here are the alternatives, and why you shouldn't use them. Corvettes: These units are wicked fast, and have twice the armour and power of a fighter. However, they also cost four times as much. So, for 20 credits, you could get twice as much armour out of four fighters than one corvette.
