FYI, not seeing this feature (or army banners on the region info page, actually) on chrome. It's there on Firefox.
As Indirik says, you probably need to put an exception for BattleMaster into AdBlock. The army banner script is called "banner_image.php", which raises red flags in most adblocking software.
You can also be pretty damn sure that Tom's never going to be serving you any actual ads.
