Gnats3

You can see your War Rank by right-clicking your Citadel. I'm not sure if the Citadel gets bigger (and thus stronger) based on the War Rank of on which Citadel upgrades you have. Right-clicking the Citadel also lets you see the upgrades you can buy to strengthen your units and buildings. These are actually called "Favor Points". You get them for getting the achievements. Look at the Achievement screen from the main menu - you will see your current favor points.
