Once the Supercomputer has been researched, you can use the Attack Calculator to compute the number of troops you need
to send for an attack. The Attack Calculator is a popup, so it cannot be used when you have any popup blocker enabled
on your computer.
Enter all the information about your intended victim and your own planet, including any troops you know you intend to send,
and click on the type of military troops you want computed. The Calculator will tell you how many additional troops of that
type you will need to succeed in your attack.
