Taken from the roladder:

With the history of 7 years dedicated Red Orchestra competitive play and hosting the most important leagues,
ladders and tournaments for the modification and Ostfront 41-45,
ROLadder.net now proudly presents the first major competition for RedOrchestra2:Heroes of Stalingrad.
The ROLadder.net OpeningCup will offer veterans and newcomers the competition to measure themselves with the best teams
from NorthAmerica and Europe.

Hopefully there will be a lot of teams entering and it will be a good way to start learning the maps etc.
