The old official documentation from EA/DICE can be found here: http://static.cdn.ea.com/dice/u/f/bfbc2 ... tor_v2.zip
A newer copy of the official documentation is locally hosted by us here: http://www.nfoservers.com/official-game ... trator.rar
Note that their documentation is a work in progress. Some of the commands won't work, and some work slightly differently than indicated.
