About the event
What kind of airsoft game is Battlegroup?
At Battlegroup, you are part of a larger force and its shared game. Faction commanders assign missions that infantry, reconnaissance teams and mechanised units carry out together at squad, platoon, company and battalion level. Players’ decisions shape how the action and the story develop.
The event combines MILSIM (Military Simulation) with elements of LARP (Live Action Role Play). You decide how deeply you want to immerse yourself in the game world. Both newcomers and experienced players are welcome.
Alongside the fighting, the game includes long movements, reconnaissance and everyday life at the base. Sometimes you wait for orders or maintain your equipment; at other times you head out on a new mission. Civilian characters and encounters bring role-playing and events beyond the battles.
The game lasts over 60 hours, so plan for rest, food and drinking water before you arrive. Most players stay at their faction’s base, where they maintain equipment and prepare for their next missions. Be ready for changeable weather and long days in the forest.
Because the game is demanding, the age limit is 18. Players aged 16–17 may apply for special permission to attend with adult players. Send a free-form application to info@ehasa.org.
More about the event
Chain of command
During the event, orders pass from the battalion commander through company and platoon leaders to squad leaders. Report in-game problems and requests to your own leader.
Combat factions play under a chain of command. Follow the orders of your leader.
Missions & story
Game control acts as the brigade and gives objectives and missions to the battalions. Each battalion commander assigns them to their troops.
Other in-game characters may offer optional side missions. Completing side missions has an impact on the game. We aim to publish game control’s major missions on status.ehasa.org so that the whole faction can see them.
Accommodation
Players sleep in their own tents at the bases, or elsewhere by prior agreement with game control. Reconnaissance platoon players may also camp anywhere in the game area.
Keep your eye protection on when sleeping in the game area or an in-game base.
Nordberg
The factions
The event has two main combat factions of nearly equal strength, distinguished by blue and yellow armbands. The commanders will be announced later. The civilian faction consists of a small group of game masters and selected assistants.

Game area & mapsChanges since the previous event
Ten planned changes to bases, missions, check-in and other game arrangements.
All 10 changes
01 / 10The GM civilian faction
The civilian faction will consist of a small group of game masters and a few selected assistants. This allows us to focus on the quality and variety of encounters and try a different approach to civilian gameplay.

02 / 10Fewer resource points and greater emphasis on respawn points
Next year, we will focus on respawn areas. Some of them and other objectives will be placed closer together with infantry gameplay in mind. Elsewhere, the distances between flag points will increase, making those areas more suitable for mechanised forces.
Read more
03 / 10Forward, capturable FOBs
We plan to add a few capturable FOBs around the map. They would provide respawn points and water, and possibly some small structures. Capturing them would take longer than normal objectives. They could also be upgraded through missions. For example, enabling vehicle respawns at a FOB could require a specific in-game item.

04 / 10A new main base
The old parking area inside the game area will become the main base of one faction. The former Lintulampi base would then return to the active game area.

05 / 10Changes to ATVs
ATVs will no longer be allowed to have machine guns, anti-tank weapons or homemade protective shields built into the vehicle itself.
Read more
06 / 10Marking cleared enemy mines
When an engineer clears an enemy mine, they mark its carrying handle with a cable tie in their faction’s colour. The tie may be removed and the mine reused only after it has been taken to the faction’s HQ or rebuilt by a civilian player with the required special ability.

07 / 10Small EHASA shops at HQs and in selected GM vehicles
