http://www.brotherhoodofvalor.com/ We have a very active group in our BF3 Division. There are no tryouts as we are open to players of all skill levels. We are a mature and respectful clan.
The majority of our members are in their 20's and either current or former military. You will find a great group of players in our BF3 Division who not only play together but work with other members on an individual basis as needed to help improve a players
skill in a variety of areas. Give it a look and I believe you will find BHV has exactly what you are looking for.
