Halli
Battlegroup takes place at the former Finnish Defence Forces training area in Halli, Jämsä. The boundary on the map shown here covers approximately 22 km², or 2,200 hectares, stretching almost nine kilometres from north to south.
Forest roads connect woodland, rocky hills and suitable base locations. Denser vegetation, drained marshes and small lakes lie between them. The road network supports vehicles and logistics, while changes in elevation and terrain make travelling through the forest different from following a road.
Across this large area, your route, transport and supplies shape the game day. In the 2026 feedback, infantry players highlighted long distances and uncertain transport as areas for improvement. Carry the supplies you need for the day and agree on movement with your squad before heading out.
