We don't have many real "airsoft fields" but we have good cooperation with police and civilian population, so we use many different terrains - some of them are in active use couple of years or more. There is a big number of themed teams, pretty big for small country, and small number of airsofters . (delete). Many of airsofters here did their time in Army, or even war, many of guys here are active soldiers, police officers, security etc.

we have like boom starting around time when ACM guns hit the market. and every day more and more people join various teams or clubs. my estimation is that we have around 500 players, but that's only my humble opinion. you could say we are still in some kind of organization.
