According to a press conference by the Dutch Army, 2500 soldiers and a great number of helicopters will be involved in a large training exercise by the Army's Airmobile Brigade at the end of September, lasting two full weeks. One of the locations used will be the TT-racing circuit in Assen, Netherlands (mimicking an airfield that has to be liberated and held by the Brigade). Other locations include regular Dutch training grounds near Schaarsbergen and Marnewaard (Groningen).
