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 30 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 20-30 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 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 TSTOS 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 TSTOS and other game series.
