CTB has a non-negotiable minimum age requirement of 18 years. We don't care how mature you think you are - if you're under 18 don't bother.
If you're interested in signing up with CTB, make a post in this forum using the following template:
1 - Your Age
2 - How you found out about CTB
3 - Did a CTB member refer you to join? And if so Who?
4 - Your location and Timezone
5 - How long you've been playing ArmA
6 - A rough idea of your availability for games (doesn't have to be 100% accurate, it's just to give us an idea)
Once you've made a post, a recruiter will contact you and organise a time to walk you through how we operate and assess if you're ready to join.
Keep in mind that our recruiters are not robots, they're real people with real lives, and things to do. They aren't going to chase you up and harass you, you have to make an effort to get on TS and get your application finished.
We highly recommend you join Battlegroup Teamspeak (ts.combatteambravo.com) and meet a few of us / play a few games before applying.
This is not a requirement, but it streamlines the process and will make your signup move a lot faster if we're familiar with you before applying.
If you have any questions, feel free to get on Teamspeak and ask a CTB member.
