The Peitsi 07 (Lance 07) manoeuvres are a joint branch exercise for operations in the nation's eastern defence district.
The Defense Forces have asked the public for patience on roads that will be heavily travelled by units taking part and causing traffic delays. This will include units moving in from Keuruu, Vekaranjärvi, Lappeenranta and Nurmes.
Local residents are also being advised of possible disturbances cause by overflights by military helicopters between the 16th and 18th of this month.
