I've done a pretty good job capturing all the various achievements and commendations. I honestly don't have many left, other than difficult-to-attain ones like Destroying Enemy Mongooses or whatever. I'm about 400,000 xp shy of SR148, and should get it within the next couple weeks at the rate I'm playing. It'd be nice to reach SR150, but I don't know how realistic that is. The double XP weekends are helping, though!
