Art of Siege is a new community platform for training would-be Rainbow Six: Siege experts.
Rainbow Six: Siege beta hopefuls can join Art of Siege and participate in a program called Field Training.
Those who prove their worth will advance to the next stage, Wall of Tactics, and secure a key to the closed beta.
The trailer below has some further details but it all makes a heck of a lot more sense if you just jump in and start training.
Rainbow Six: Siege hits PC, PS4 and Xbox One on December 1.
