Game area: Ilveskallio

We chose the Finnish Defence Forces training grounds as the game area. The game area is located in Hattula not far away from Hämeenlinna.

The Game area suits well for this kind of big airsoft event because of its big size and good roads.

There are Finnish defence forces buildings in the area that are fenced and marked as banned areas in the map. If you can see the fence, leave it immediately, so you do not cause an unnecessary alarm.

Realisation of the event

What kind of game is Battlegroup?

  • The Battlegroup -game series is a combination of airsoft, milsim and larp elements. The game can be compared to the Swedish Berget–events.
  • The game is filled with ongoing operations and momentary missions, which are handed out by the team leaders.
  • The game will not be full on battle the whole time, there will also be some times you won't be able engage in battle.
  • The players are there for different kinds of experiences, so try to mind the civilians and other special role -players.
  • Players should be physically and mentally prepared that the game will last +90 hours and the game area being big. This means the players should be well equipped for long distances, long times on the battlefield, weather changes and that food and water will not always be on hand.
  • You don't necessarily have to have any experience in airsoft before the event, but being in the military or being a scout is recommended in this case. If you are in doubt that you can survive Battlegroup -game, we encourage you to take part in other smaller events before arriving to the game.
  • The official in game languages are finnish and english

Structure of command

  • The Battlegroup -game series is pretty much based on the commands the battalion commander gives to their sub-commanding officers ergo company commanders/ platoon leaders. They will then forward the missions and instructions to the group leaders. The information travels both ways, so if you or your team has an in game issue/request please share it with your commanding officer and not directly with the battallion commander. This will ensure that the battallion commander isn't overwhelmed with all kinds requests from many sources.
  • All in game battling factions have a structure of command, which all have their leaders. The players are expected to obey the commands of their commanding officers. This is not a game for loners, where just everyone is looking at their own best intrests.
  • If you and/or your team is not happy with something, please be in contact with your commanding officer or if neccesary with his/her commanding officer.
  • Remember that every player is attending the game at their own free will and that everyone should be allowed to enjoy their experience.
  • Remember to join your own factions facebook-group before the game. This will ensure that you get all the information needed to attend the game.


  • The battalion commander hands out the missions for his team. The Game masters will hand out larger obejctives and smaller missions. Other in game characters might also give out missions for players to be completed voluntarily.
