Welcome!

The 21st Vikings is an international Arma 3 Tactical Realism Unit, predominantly focused on infantry warfare, with members primarily located in the United States and various European countries.

  • Since 2014
  • Minimum Age: 18
  • Our Goal: Immersion, Casual yet Disciplined
  • Dedicated Servers
  • Current size: 1 or 2 fire teams per operation
  • Inexperienced and New Players Welcome. We're here to help!
  • Difficulty: No crosshairs, no third-person, ACE advanced medical system, etc.
  • We provide realistic military experience without the 'yes sir'


If you're new to Arma 3 or tactical realism the above may sound harder than it is. We are happy to help you get started and we don't expect anyone to be a great player from the start. Although being good at tactical realism requires some training it mostly requires experience. We have experience training new players from all walks of life.

Our gameplay is fairly casual. However, we do maintain basic discipline during our operations and training events, simply to keep things organized. We appreciate a good joke and having a laugh, but don't tolerate unnecessary drama or toxicity.


Weekly Events:

  • Friday Night Operation (Deployment) @ 22:00 GMT(+1 during DST)
  • Saturday Night Operation @ 22:00 GMT(+1 during DST)
  • Tuesday Mini-op @ 21:00 GMT(+1 during DST)
  • Training Sunday @ 20:00 GMT(+1 during DST)

Operations or training events are never mandatory. Minimum attendance we expect is once a month.

In addition, our members may always jump on our dedicated server throughout the week outside of main operation and training times, to improve their skills and have fun alongside their fellow members. Members are encouraged to come on to TeamSpeak and play other games as well, either with our members or their own friends.

Training & Ranks

New members receive 30 minutes of Basic Combat Training (BCT). After successfully completion they are allowed to join main operation and training events. Training is never mandatory after that point. Nonetheless, since we don't rise to the level of our expectations but fall to the level of our training, we offer training to our dedicated members:

  • Combat Infantry Training (expert infanry skills)
  • Certifications (small courses) for specialty roles such as Team Leading, Squad Leading, Combat Corpsman, Combat Diver, Designated Marksman, Sniper, Pilots, Mortar Specialist, UAV Operator, etc.
  • Training Dept. with experienced members willing to help


Our rank system is mainly based on the amount of operations and training events you've participated in, so your rank says most about your dedication. You can also earn medals by going above and beyond the call of duty during main operations.
