There's currently little information about it, but I did sort of go into it on the BF3 talk page.

"The PLR might be the remnants of the Russian rebels and the insurgent faction in BF2. BF2 takes place around 2007 (according to the Wake Island 2007 map), after all. If the MEC was disbanded or otherwise damaged, it's possible that they became the primary harbor for the PLR. (which would explain why the U.S. would go in to occupy the MEC in 2014, as the PLR would basically be an organization formed by a bunch of organizations which hate the Western world and Russia.) As for why Russia is still fighting the U.S. -- well it's quite possible that hostilities between them and the EU and US never ceased following the defeat of the MEC and PLA, and that one Spetsnaz or Marine with a chip on their shoulder took some pot-shots at their enemy even while they were dealing with the PLR (why both sides might be in paris), which could have ignited the entire Operation Metro fiasco. (think of a Gettysburg type of scenario. That battle began with some Confederate scouts just looking for shoes, and it blew up into one of the most important battles of the American Civil War). Of course, this is all just speculation, or an educated guess based upon the events and background of BF2"
