That's explained on Page 38. You 'rank up' after spending a set amount of XP - in this case, Rank 2 begins at 7,000 XP. We started with 5000 XP (4500+500 initial freebies), so once TGT has awarded us and we have spend 2,000 XP (so roughly a month if this is consistent), we will be Rank 2.<br/><br/><br/>Amusement: At rank 6, I would be able to Dodge at /100. Can't touch this!
