Battlegroup events, which are known by Finnish players as TSTOS (Taisteluosasto) events, have generally been attended by nearly a thousand players from Finland and abroad all the way from Sweden to Brazil. The event takes several days, without the game situation being interrupted separately. The main faction bases are calmed down at night to ensure a sufficient rest. Tens of different vehicles, such as even real life armored vehicles, off-road vehicles, SUVs and ATVs, participate in a single Battlegroup event. Most of the vehicles are involved in the game and can be destroyed by separate anti-tank weapons. Compared to similar events in the world, we are one the longest event. In the number of participants, we represent the biggest airsoft events in Europe.
The content of the events
What happens in the event takes place in an imaginary world with mostly imaginary factions and nations created by the game masters. Our goal is to combine military simulation, standard airsoft, and thrilling features, creating a very cinematic and overall realistic experience. Players may appear in the event as soldiers of the fighting parties, civilians, and different in-game organizations and groups. Depending on the faction, players will be led by volunteered team and platoon leaders, company commanders and battalion commanders.
Partners
Ehasa ry works closely with other associations and federations (MPK and Reserve Sports Association), municipalities (Padasjoki, Hämeenlinna, Jämsä) and authorities (Defense Forces, Police, Rescue Service and Finnish Forest Administration). In 2016-2018 we organized cources in co-operation with the National Defense Training Association (MPK). The assistant organizers from MPK were involved in the Ehasa organization as a part of MPK’s “Basics of organizing a exercise part 2” course. The purpose of the course was to learn the organization of public events, which is comparable, for example, organizing of large military exercises. Participants in the course did benefit most from the training paid by Ehasa, such as the Finnish red cross First Aid Card and the Community Service Officer card. In 2019, we organized the first Battlegroup event in Padasjoki and also the first event without MPK cooperation because of changes in their structure.

What is Ehasa?
Ehasa or the old East Helsinki Airsoft Association is originally a registered association established in Helsinki, whose task was to organize local airsoft weekend games. Since 2010, we have moved to organize ever-growing events, which we have now organized over 50 times in different parts of South and Central Finland.
We are currently organizing the biggest events in Finland, and many enthusiasts of the sport know the reputation of Ehasa and have participated at least in one of our events. The cornerstone of our association is fast and active customer service, feedback-responsive event development, and ambition to always make events better for all of our participants.
To facilitate our operations, we have created many different programs and services, such as a kuulaportti -registration system and status.ehasa.org flag tracking system, which both are also partly available to other airsoft event organizers.
Our association consists of +20 young adults about 25-35 years of age, with the know-how of different fields and the desire and vision to take Finnish airsoft events forward. We also have few active military and military reserve members and as a result of that we have ended up in cooperation with different reserve associations.
Our regular events can be organized by ourselves, but the Battlegroup game series also requires assistance from non-members. For this reason, we have a separate recruitment page, through which you can apply as an assistant to our Battlegroup and other game series.
