An Estonian Defense Forces soldier from Company C, Single Scouts Infantry Battalion looks up a stairwell in search of soldiers role-playing as insurgents Sep. 4 at Murru Vangra, an abandoned prison in Rummu, Estonia. The Estonian Scouts Battalion rehearsed with American paratroopers from the 173rd Airborne Brigade in preparation for a night raid training mission at the prison. The raid was part of Steadfast Javelin II, a NATO exercise involving more than 2,000 troops from nine nations conducting various training missions across Estonia, Germany, Latvia, Lithuania and Poland. The exercise focuses on increasing interoperability and synchronizing complex operations between allied air and ground forces through airborne and air assault missions.
